Lab-on-a-Chip and BioMEMS Devices
|
|
Lab-on-a-chip devices (also known as
micro-total-analytical systems or microTAS) are
devices designed to miniaturize analytical or
bioanalytical techniques and integrate them
into a microfabricated format. Techniques such as chemical separations
(electrophoresis, chromatography, etc) or immunoassays
are incorporated into
microfabricated systems (typically glass, silicon or polymers) with a goal of increasing
performance, minimizing reagent requirements, and decreasing cost.
BioMEMS devices are similar,
typically focusing on MEMS (microelectromechanical systems)
with biological applications.
We use lab-on-a-chip devices to capture, sort, culture, or
study cells, study interfacial phenomena, and produce pharmaceuticals.

We use laser-microfabrication to make microscale polymer elements within
etched microchannels, for use for
microfluidic control
or
dialysis.
A frequency-tripled Nd:YAG laser is used to photopolymerize a liquid-phase solution
of monomers, solvents, and photoinitiators. The structural, tribological, and chemical
properties of the resulting solid polymer structure are controlled by the material
precursors.
