Mesh-integrated microdroplet array for simultaneous merging and storage of single-cell dropletsElectronic supplementary information (ESI) available. See DOI: 10.1039/c2lc21266h

We constructed a mesh-grid integrated microwell array which enables easy trapping and consistent addition of droplets. The grid acts as a microchannel structure to guide droplets into the microwells underneath, and also provides open access for additional manipulation in a high-throughput manner. Each droplet in the array forms a stable environment of pico-litre volume to implement a single-cell-based assay. A single-cell-based assay is demonstrated using a mesh-integrated microwell array which enables easy trapping and consistent addition of droplets in a high-throughput manner.
