Abstract

A microfluidic system was developed and combined with optical tweezers for single cell sorting. This system consists of a glass chip of 300 μm thickness with an etched crosswise channel structure, a silicon layer for sealing and a PMMA substrate for tubular coupling. Selected cells are trapped and moved in perpendicular direction to the main flow for recovery in special reservoirs and further evaluation (e.g. by polymerase chain reaction, PCR). In addition, maximum light doses and exposure times for maintaining cell viability were determined.
