Nanoplasmonic Biosensors: From Innovative Materials to Multimode Sensing with Integrated Microdevices
Amy Shen, Professor, Okinawa Institute of Science and Technology, Japan

Gold nanostructures are a highly attractive class of materials with unique electrochemical and optical sensing properties. Recent developments have greatly improved the sensitivity of optical sensors based on metal nanostructured arrays. We introduce the localized surface plasmon resonance (LSPR) sensors and describe how its exquisite sensitivity to size, shape and environment can be harnessed to detect molecular binding events. We then describe recent progress in three areas representing the most significant challenges: integration of LSPR with complementary electrochemical techniques, long term live-cell biosensing and practical development of sensors and instrumentation for routine use and high-throughput detection. As an example we will demonstrate a novel refractive index and charge sensitive device integrated with nanoplasmonic islands to develop nano-metal-insulator-semiconductor (nMIS) junctions. The developed sensor facilitates simultaneous detection of charge and mass changes on the nanoislands due to biomolecule binding. A brief insight on microcontact printing to functionalize proteins on nanoplasmonic sensors will also be discussed. The developed nanosensors can readily be adopted for multiplexed and high throughput label-free immunoassay systems, further driving innovations in biomedical and healthcare research.

Single Molecule Screening
Joshua Edel, Professor, Imperial College London, United Kingdom

Analytical Sensors play a crucial role in today’s highly demanding exploration and development of new detection strategies. Whether it be medicine, biochemistry, bioengineering, or analytical chemistry the goals are essentially the same: 1) improve sensitivity, 2) maximize throughput, 3) and reduce the instrumental footprint. In order to address these key challenges, the analytical community has borrowed technologies and design philosophies which has been used by the semiconductor industry over the past 20 years. By doing so, key technological advances have been made which include the miniaturization of sensors and signal processing components which allows for the efficient detection of nanoscale object. One can imagine that by decreasing the dimensions of a sensor to a scale similar to that of a nanoscale object, the ultimate in sensitivity can potentially be achieved - the detection of single molecules.

Silicon Nanotechnology Meets Biology (Smaller and Wetter is Better)
Gregory Timp, Keough-Hesburgh Professor of Electrical Engineering & Systems Biology, The University of Notre Dame, United States of America

According to Moore’s law, the scaling of silicon integrated circuits is supposed to reach the 5 nm-node sometime after 2020, although the schedule is still problematic due to the astronomical cost and atomically precise line-rules. On the other hand, biology has been performing cost-effectively using proteins the size of 5 nm (and smaller) that fold with atomic precision for 4.28 billion years now—it is a robust and proven technology, albeit wet. In this talk, it is argued that there is still “plenty of room at the bottom” for improving performance if silicon nanotechnology is adapted to biology. With silicon nanotechnology it is now within our grasp to create an interface to biology on a nanometer-scale. Three examples of such interfaces are proffered. The first is a liquid flow cell that works like an envelope made from 30 nm-thick silicon nitride membranes, which can hold and sustain living cells in medium and yet fits inside a Scanning Transmission Electron Microscope (STEM). In a STEM, the liquid cell can be used to visualize and track live cell physiology like a phage infecting a bacterium with nucleic acids at 5 nm resolution. The second is a nanometer-diameter pore sputtered through a silicon nitride membrane 10-nm-thick that can be used to transfect cells precisely with nucleic acids to affect gene expression in them and, under different bias conditions, detect protein secretions from single cells with single molecule sensitivity. The secretions inform on the cell phenotype and offer a molecular diagnosis of disease. Finally, the third interface is a sub-nanometer-diameter pore, which is about the size of an amino acid residue, in either silicon dioxide or silicon nitride membranes ranging from 6 to 10 nm-thick.  Sub-nanopores like this have been used to read the primary structure of a protein, i.e. the amino acid sequence, with low fidelity, but with single molecule sensitivity, vastly outstripping the sensitivity of conventional methods for sequencing such as mass spectrometry. Taken altogether, the prospects are dazzling for a new type of integrated circuit that incorporates biology with state-of-the-art silicon electronics.

Towards Wearable Real-Time Clinical Monitoring Using Microfluidic Devices
Martyn Boutelle, Professor of Biomedical Sensors Engineering, Vice Chair Department of Bioengineering, Imperial College London, United Kingdom

Modern acute critical care medicine is increasingly seeking to protect vulnerable tissue from damage by monitoring the patterns of physical, electrical and chemical changes taking place in tissue – so called multimodal monitoring. Such patterns of molecular changes offer the exciting possibility of allowing clinicians to detect changes in patient condition and to guide therapy on an individualized basis in real time. Microfluidic lab-on-chip devices coupled to tissue sampling using microdialysis provide an important new way for measuring real-time chemical changes as the low volume flow rates of microdialysis probes are ideally matched to the length scales of microfluidic devices. In this presentation, I will describe the combination of miniature electrochemical sensors and biosensors with 3D printed microfluidic devices for transplant organ and patient monitoring. Concentrations of key biomarker molecules can then be determined continuously using either optically or electrochemically, using amperometric, potentiometic and array sensors.  Wireless devices allow analysis to take place close to the patient. Droplet-based microfluidics, by digitizing the dialysis stream into discrete low volume samples, both minimizes dispersion allowing very rapid concentration changes to be measured, and allows rapid transport of samples between patient and analysis chip. This talk will overview successful design, optimization, automatic-calibration and use of both continuous flow and droplet-based microfluidic analysis systems for real-time clinical monitoring, using clinical examples from our recent work.

Microtubular NEMS for On- and Off-Chip Microfluidic Applications
Oliver Schmidt, Professor & Director, Leibniz-Institut für Festkörper- und Werkstoffforschung, Germany

Microtubular MEMS with outstanding properties are self-assembled into fully functional and integrative microtubular architectures. This makes them attractive for a broad range of applications and scientific research fields ranging from novel hybrid heterostructure devices to 3D microsystems both on and off the chip. Microtubular MEMS are exploited to construct ultra-compact and ultra-sensitive advanced electronic circuitry, sensors and optofluidic components around fluidic channels towards the implementation of a lab-in-a-tube system. They are also useful to study basic mechanisms of single cancer and stem cell migration, growth and mitosis in realistic 3D confined environments.  Off-chip applications include biomimetic microelectronics for regenerative cuff implants and the development of hybrid microbiorobotic motors for paradigm shifting reproduction technologies.

Integrated Optofluidic Devices for Manipulation and Imaging of Cells
Roberto Osellame, Professor, Politecnico di Milano; Senior Researcher, Institute for Photonics and Nanotechnologies (IFN) – National Research Council (CNR), Milan, Italy

Single cell analysis aims at unravelling the biological complexity due to the well-recognized diversity in cell populations. The integration of optical forces with microfluidic networks, in so-called optofluidic chips, allows advanced cell manipulation and characterization. In addition, the development of microscopy on a chip for the 3D tomography of single to few cells agglomerates paves the way to rapid analysis of a large quantity of samples for drug screening and personalized medicine.


Diffusion-induced Interfacial Phenomena in Microfluidics
Anderson Shum, Associate Professor, University of Hong Kong, Hong Kong

Interfacial phenomena are ubiquitous in both natural systems and technologies. In this talk, I will discuss interfaces formed between two immiscible aqueous liquids. Since molecules can diffuse through these interfaces relatively easily, massive diffusion can happen across them. Together with the control provided by microfluidic devices, interfacial phenomena induced by diffusion can be systematically investigated. I will demonstrate how control of osmotic diffusion enables manipulation of emulsion droplet morphology as well as polyelectrolyte particles and capsules. These diffusion-controlled formation processes should also be applicable in more macroscopic, non-microfluidic settings, and hence have great potential to fabricate new encapsulating structures.

Extracellular Vesicles (EVs) and Cell Free DNA (cfDNA) as Blood-based Biomarkers: Plastic-based Microfluidics for their Enrichment and Analysis
Steve Soper, Foundation Distinguished Professor, Director, Center of BioModular Multi-scale System for Precision Medicine, The University of Kansas, United States of America

While there are a plethora of different blood-based markers, EVs are generating significant interests due to their relatively high abundance (~1013 particles per mL of blood) and the information they carry. EVs contain a diverse array of nucleic acids, such as mRNA, lncRNA, and miRNA that can be used for disease management. In addition to EVs, cfDNA also are biomarkers that can be used to help manage different disease states using the mutations they possess that can have high diagnostic value. In spite of the relatively high abundance of cfDNA in diseased patients (~160 ng/mL), the extraction and enrichment of cfDNA has been inefficient, even by commercial kits, due to the low abundance of the tumor bearing DNA fragments (<0.01%) and the short nature of these fragments, especially cancer-related cfDNA (as small as 50 bp). In this presentation, we will discuss the design, fabrication and analytical figures-of-merit of a microfluidic device that can serve the dual purpose for the affinity-based selection of EVs and the solid phase extraction of cfDNA directly from plasma using the same device. The microfluidic is made from a plastic that can be injection molded to produce high quality devices at low cost. For EVs, the device is made cyclic olefin copolymer (COC) is UV/O3 activated to allow for the efficient immobilization of affinity agents to the surface of the device. In the case of cfDNA, the device is made from COC as well, but is only UV/O3 activated (i.e., no affinity agents used). Information will be provided as to the ability to molecularly profile the cargo contained within the affinity-selected EVs, in particular mRNA expression profiling. We will also discuss the use of this microfluidic to isolate with high recovery cfDNA from plasma samples with size selection capabilities. The isolated cfDNA could be queried for mutations using an allele-specific ligation detection reaction at a mutant to wild-type ratio <0.1%.


Scale-up and Sustainability for Large and Small Microfluidic Laboratories
Maiwenn Kersaudy-Kerhoas, Associate Professor, School of Engineering and Physical Sciences, Heriot-Watt University, United Kingdom

The rapid translation of research from bench to bedside, as well as the generation of commercial impact, has never been more important for both academic and industrial researchers. We propose low-capital investment and sustainable rapid-prototyping solutions for almost all LOAC applications, with potential to accelerate microfluidic research and technology acceptance dramatically.

Microfluidic Flow Control for LOAC: Bio-Inspired Engineering
Jaap den Toonder, Professor and Chair of Microsystems, Eindhoven University of Technology, Netherlands

Control of fluid flow at small length scales (typically < 1 mm) i.e. “microfluidics”, is important for many applications. Examples are devices for healthcare diagnostics, in which complex tasks of (bio-)fluid manipulation and detection need to be performed; organ-on-a-chip devices in which suitable micro-environments for multicellular tissue structures need to be  created; water quality monitoring chips for continuous detection of bacteria, algae and chemicals; and manipulation of fluids droplets over surfaces. We are developing new technologies for active control of microfluidic flow in these applications. In doing this, we are inspired by nature in which a variety of microfluidic manipulation principles can be recognized.

Frontier in Direct Observation and Visualization of Molecular Interactions
Gijs Wuite, Professor, Vrije Universiteit Amsterdam, Netherlands

The genetic information of an organism is encoded in the base pair sequence of its DNA. Many specialized proteins are involved in organizing, preserving and processing the vast amounts of information on the DNA. In order to do this swiftly and correctly these proteins have to move quickly and accurately along and/or around the DNA constantly rearranging it. In order to elucidate these kind of processes we perform single-molecule experiments on model systems such as restriction enzymes, DNA polymerases and repair proteins. The data we use to extract forces, energies and mechanochemistry driving these dynamic transactions. The results obtained from these model systems are then generalized and thought to be applicable to many DNA-protein interactions. In particular, I will report on a new single molecule methods. I’ll introduce Acoustic Force Spectroscopy (AFS). With AFS we extend the force-spectroscopy toolbox with an acoustic manipulation device that allows exerting acoustic forces on tethered molecules. AFS is a Lab-on-a-chip device consisting of a flow cell of two glass plates with a fluid chamber in between and a piezo element glued on top. While applying an alternating voltage to the piezo element, forces from sub-pN to hundreds of pNs are exerted to thousands of biomolecules in parallel, with sub-millisecond response time and inherent stability. AFS distinguishes itself by its relative simplicity, low cost and compactness, which allow straightforward implementation in lab-on-a-chip devices. I’ll discuss the application of this technique to DNA-protein interaction as well as for antibody-protein interaction detection and for its use to quantify cell adhesion.


Rapid Prototyping in Microfluidics: New Perspective by New Materials
Bastian Rapp, Principal Investigator and Head of NeptunLab, Karlsruhe Institute of Technology, Germany

Microfluidics is a very important discipline for many disciplines including, among others, synthetic and analytical chemistry, biochemistry and biology. However, the design of most microfluidic systems has remained largely unchanged since the introduction of soft lithography. In academia, microfluidic systems made from polydimethylsiloxane (PDMS) have become the de-facto standard. These are usually created in a replication process from a photolithographically structured layer of photoresist. However, in many applications fast concept-to-chip intervals are required for efficient experimental throughput and optimization. This is where 3D printing and additive manufacturing (AM) can make a significant contribution. We recently introduced “Computer Aided Microfluidics (CAMF)” a process that allows the conversion of digital chip layout to a testable physical structure in less than a day [1]. Using digital models allows a streamlined manufacturing process with digital models first being evaluated by numerical simulation before being transferred to a physical structure in a one-step manufacturing process. We recently expanded the material choice for CAMF to include glass [2] (which is created by sintering from photocurable glass prepolymers) and thermoplasts, most notably polymethylmethacrylate (PMMA) for which we created photostructurable precursors. This allows the rapid manufacturing of microfluidic systems in materials which have a long history in microfluidics and have been thoroughly investigated. We will demonstrate the advantages of this prototyping method and its potential use in many aspects of life sciences and analytics.


LSC-PM: A Biomimetic Approach to Increase Solar Harvesting for Synthetic Chemistry
Timothy Noel, Associate Professor, Eindhoven University of Technology, Netherlands

In this lecture, we will discuss a novel device integrating the luminescent solar concentrator (LSC) concept with photomicroreactors (LSC-PM), allowing the direct use of solar light in photochemistry without the need for any intermediate energy conversion. This device is capable of capturing direct and diffuse sunlight, converting it into a narrow wavelength and delivering it to the embedded microchannels.


Fluids for Theranostic Cell-based Analytics
William G Whitford, Strategic Solutions Leader Bioprocess, GE Healthcare Life Sciences, United States of America

Theranostics is employing newer technologies including microfluidic-based or 3D printed analytics requiring the maintenance of animal cell viability and phenotype. These require a robust source of appropriate, validated and regulated maintenance fluids or culture media.


Tissue Microprocessing: Shaping Sub-nanoliter Volumes of Liquids on Tissue Sections for Multimodal Analysis
Govind V Kaigala, Research Staff Member, IBM Research Laboratory-Zurich, Switzerland

In contrast to standard microfluidics, which are typically closed, we are developing a scanning, non-contact microfluidic technology that can shape liquids in the "open space" over surfaces. This technology utilizes a microfluidic probe (MFP) having microfabricated structures for localizing a liquid of interest on a surface using hydrodynamic flow confinement. MFP permits patterning surfaces with proteins and other biomolecules in an additive and subtractive manner, forming complex gradients on surfaces, and interacting with cells on surfaces. With flow confinement operating at volumes smaller than 1 nanoliter, a few cells can be targeted in a human tissue section for the specific staining of disease markers.  This confinement concept has also been scaled for targeting 1000’s of cells. Flow confinement and efficient use of chemicals can be further optimized using a concept called "hierarchical" hydrodynamic flow confinement.  I will show how this family of liquid scanning probe devices is evolving as a bioanalytical tool to alter the physics and chemistry of biological interfaces at the micrometer to centimeter-length scales. I will also propose concepts pertaining to tissue microprocessing encompassing local phenotyping for interrogating tumor heterogeneity and spatially resolved molecular profiling which may contribute to the multi-modal analysis of critical biopsy samples in the context of next-generation pathology.

High Resolution 3D Printing Inside a Chip
Aleksandr Ovsianikov, Professor, Additive Manufacturing Technologies, Technische Universität Wien, Austria

3D printing opens exciting perspectives towards rapid engineering of complex 3D structures for microfluidic applications. In this context, multiphoton lithography (MPL) is an outstanding approach, since photosensitive material formulations and cells are delivered by perfusing the channels, thus enabling 3D printing within already assembled microfluidic chips. The latter aspects implies that different materials, construct geometries and cell types can be tested with the same set of chips without changing their initial design or fabrication process. In addition MPL offers high spatial resolution, unmatched by other 3D printing approaches, and can produce features down to sub-100 nm level directly in the volume of the material, without the necessity to deposit it layer by layer. An increasing portfolio of available materials enables utilization of the versatile capabilities of MPL, from producing complex volumetric 3D structures by means of cross-linking, to creating void patters within hydrogels already containing living cells. In this contribution, our recent progress on MPL for microfluidic applications and the development of according materials will be presented.
