Abstract

The disclosed technology includes devices and methods for detecting rare cells in whole blood samples using a microfluidic device. Such devices include a housing with a microfluidic chamber having first and second microfluidic layers, each microfluidic layer having an array of microscale structure. Other disclosed devices also include a housing including a chemically functionalized hydrogel matrix and a pump connected to the housing. Disclosed methods include constructing, with an additive manufacturing device, a microfluidic device having a microfluidic chamber, removing, by a thermal release process, at least some of the sacrificial support material deposited by the additive manufacturing device, and chemically functionalizing at least a portion of the microfluidic chamber. Other disclosed methods include chemically functionalizing a hydrogel matrix and connecting the chemically functionalized hydrogel matrix to a pump.
