Optoelectronic Tweezers Micro‐Well System for Highly Efficient Single‐Cell Trapping, Dynamic Sorting, and Retrieval (Small 23/2024)

Optoelectronic Tweezers In article number 2307329, Lin Feng and co-workers constructed a novel microfluidic chip based on an optoelectronic tweezers system, comprising micro-well array integrated with a photo-conductive plate. This method enables the parallel capture of cells, forming effective cell arrays in a continuous flow. It also allows for the light-guided single-cell retrievals by modulating the electric field and generating a negative dielectrophoresis force in the target micro-well.
