Abstract

Microfluidic systems and methods to generate and analyze microcapsules comprising biological sample, such as for example, single cells, cellular contents, microspore, protoplast, are disclosed. The microcapsules comprising the biological sample can be preserved by a polymerization process that forms a hydrogel around the biological sample. The hydrogel microcapsules can be trapped in a trapping array or collected in an output reservoir and subject to one or more assays. The trapping array or the output reservoir can be disposed over a porous layer that can filter the continuous phase (e.g., oil) in which the microcapsules are dispersed in the microfluidic device. The pores of the porous layer are configured to be smaller than the size of the microcapsules to prevent the flow of the microcapsules through the porous layer.
