Abstract

Selective droplet sampling system which can deliver target droplets to five different chambers is realized by pneumatically controlled horizontal PDMS microvalves. One inlet and five outlets sorting are performed by only two pneumatic valves using the high aspect ratio flexible parallel PDMS wall structures. Selective droplets sampling is obtained with outlet flow resistance control by deformable horizontal microvalves and walls. The proposed simple flow control structure enables total flow system with simple fabrication by a single PDMS molding. The sampling was performed within 1 second under pneumatic pressure from 0 kPa to 250 kPa.
