Abstract

original image

A new method for sorting loaded microstructures using a platform known as active rail is presented. Active rail actively sorts grooved hydrogel microstructures at channel branch sites through pneumatic activation of a flexible rail. This paper provides a sorting mechanism that is capable of continuous flow reconfigurable multibranch guidance, and it demonstrates stacking of microstructures for combinatorial multicompartment chemical delivery.
