We have been developing tools for the diagnosis of a variety of
diseases. The commonality in these tools is that they consist of
microfluidic devices made from plastics via injection molding. Thus, our
tools can be mass produced at low-cost to facilitate bench-to-bed side
transition and point-of-care testing (PoCT). We have also been
generating novel assays focused on using liquid biopsy samples that are
enabled using microfluidics. In this presentation, I will talk about the
evolution of our fabrication efforts of plastic-based microfluidic and
nanofluidic devices as well their surface modification to make the
devices biocompatible for in vitro diagnostics. One tool that we have
generated is a plastic device (38 × 42 mm) that consists of 1.5M
pillars, which are surface decorated with affinity agents targeting
certain disease-associated extracellular vesicles (EVs). The affinity
agents are covalently attached to the surface of the microfluidic device
using a bifunctional linker, which consists of a coumarin moiety to
allow for the photolytic release of the captured EVs using a blue-light
LED to minimize photodamage to the EVs’ molecular cargo. We have also
developed a high-throughput nano-Coulter counter (nCC) made from a
plastic via injection molding for the counting of captured EVs from
clinical samples to allow their enumeration. The nCC consists of
multiple pores that are ~350 nm to allow for high throughput counting
with exquisite LODs (500 EVs/mL). In this presentation, I will discuss
the utility of these microfluidic and nanofluidic devices in several
diseases, for example, using EVs as a source of mRNAs for molecular
sub-typing of breast cancer patients. EVs were affinity selected from
breast-cancer patients’ plasma by searching for both epithelial and
mesenchymal expressing EVs to allow for highly efficient sub-typing
using the PAM50 gene panel. In an addition, the microfluidic and
nanofluidic devices were integrated into a single platform
(modular-based system) for PoCT to screen for early stage ovarian
cancer. Affinity probes were used to target EVs specifically generated
from tumor cells that signal early-stage ovarian cancer disease with the
nCC used for enumerating the number of EVs captured. Finally, the
modular system was used for the detection of COVID-19 at the PoC by
affinity selecting SARS-CoV-2 viral particles. The integrated system
could process saliva samples to search for the viral particles and count
them in <20 min.
