Tackling the Global Health Threat Posed by Fungal and Oomycete Diseases Using Lab-on-a-Chip Devices
Ayelen Tayagui, Research Fellow, University of Canterbury, New Zealand

Lab-on-a-Chip devices can enhance the study of disease-causing microorganisms and tackle their effects on global health.  We describe the design, manufacture and use of devices use to study the forces these organisms use to to infect their hosts.

Towards Continuous Cytokine Monitoring in Organ-based Platforms
Maud Linssen, Researcher, Eindhoven University of Technology (TU/E), Netherlands

Investigations on organ-based platforms such as organoids, organ-on-a-chip, and transplantation organs, require monitoring strategies in order to optimally control the biological systems. However, there is a lack of tools to continuously measure specific low-concentration biomarkers with minimal perturbation. Biosensing by Particle Motion (BPM) is a sensing method with single-molecule resolution that has been specifically designed to enable the continuous monitoring of biomolecules at low concentrations, such as nucleic acids, metabolites, proteins and hormones. The method relies on tracking the motion of individual biofunctionalized particles (1 µm in diameter) that interact with a biofunctionalized substrate. The particles switch between bound and unbound states due to reversible single-molecule interactions, dependent on the presence of analyte molecules. Recently, sampling by microdialysis has been investigated [3]. In this paper we present the development of a BPM sensor to measure cytokines, exemplified with the detection of Interleukin-6 and TNF-a. We will present a study of molecular binders and coupling strategies, focusing on sensitivity and reversibility of the sensor. Furthermore, measurements with microdialysis will be shown. Finally, we will discuss the prospects of using BPM and microdialysis for the continuous monitoring of low-concentration biomarkers in organ-based platforms.

ElectroMed – A Programmable Peptide/Protein Screening Platform for Immunology
Cesar Pascual García, Lead Research Scientist, Luxembourg Institute of Science and Technology

Immunology has advanced significantly in recent years thanks to a better knowledge of molecular protein recognition, which has allowed for the creation of innovative treatment options such as genetic vaccines and cell therapies. However, there is a need to accelerate the process of epitope recognition by proteins in order to generate personalized therapies. ElectroMed has been a project with six European partners in which we created a concept for a programmable peptide screening platform based on an array of Immuno-FET sensors with programmable peptide receptors synthesized in-situ using electrochemically generated acid.

A proof-of-concept has been demonstrated by controlling the deprotection of acid labile groups, which enables a high purity synthesis of crude peptides. We remove diffusion-limited processes in chemistry by automating the peptide synthesis and using microfluidic flow in-situ synthesis in planar sensors, allowing us to expedite time to results. FET sensors have the potential to provide online quality control of peptide synthesis by detecting the fingerprints of acid labile group protection and deprotection, as well as superior information quality because label-free sensors can provide kinetic information.

In conclusion, our approach has the potential to speed research into peptide protein screening of linear peptide sequences. In this talk we will review our results and provide the context for the applications in immunology.
