Microencapsulation can be used for high-throughput (HT) processing of bacterial libraries. Ideally, each microcarrier would contain exactly one cell or colony. However, synthesis yields a mixture of capsules containing the desired one cell,  multiple cells and empty microcarriers. E. coli cells expressing green fluorescent protein (GFP) were encapsulated in 35 nl Hydrogel carriers. HT sorting procedures by a COAPS sorter were then used to enrich samples to 95% monoclonality.
