ABSTRACT


We characterize a droplet-based biochemical reaction device with the features of droplet self-positioning, self-mixing and self-alignment optics on a micro-patterning PDMS chip. The phenomenon of droplet self-positioning is explained as follows: the different texture zones generate gradient of surface tension force to manipulate droplet. Droplet-based reagents can be transported, precisely positioning, and mixed on the detection zone without any power source. The study was carried out to experimentally determined triglycerides (TG) using this droplet manipulation device with correlation coefficient 0.922 from 19 mg/dl to 480 mg/dl.


Keywords: Droplet Manipulation, Droplet Self-mixing, Triglycerides Assay
