Abstract

We developed a spatially focused reagent injection system with improved 3-D sheath flow scanner. SiO2 mesh strainer is formed in the microwell to improve spatial resolution of the reagent flow. This enables selective delivery of the reagent to target cell colonies cultivated in the microwell. To fabricate the SiO2 mesh strainer, sacrificial layer etching of Si micro pillars is employed. Simulation and experimental results confirmed that a use of the mesh strainer improves spatial resolution of the induced reagent successfully.
