Droplet-based Microtexture Biochip System for Triglycerides and Methanol Measurement.

A droplet-based microfluidic system was developed for biochemical assays of triglycerides and methanol as potential applications in medical rapid diagnostics and food safety. We present a novel platform to manipulate biology reaction droplets with features of self-moving, self-mixing, and self-positioning toward the detection spot. The driving force comes from the gradient of surface tension force generated by the hydrophobic microtexture PDMS surface.
