Abstract

We have developed on-chip sorting systems using sol-gel transition of the thermo-reversible gelation polymer (TGP) as carrier flow controlled by the focused infrared (IR) laser [1]. For efficient sorting, we achieved size and position control of sample core flow in three-dimensional (3D) sheath flow. Stable control was realized under wide range of Reynolds number (Re) from 0.1 to 115 by optimizing channel structures of sample and carriers inlets. We applied this device for sorting system of yeast cells expressing green fluorescent protein (GFP). The yeast cells were successfully separated with accuracy of more than 82.1% and purity of more than 97.5%.
