Fig. 1. (a) Exploded view of the microfluidic chip. The chips are made up of three PDMS layers: the top layer contains the reaction wells and microchannels, the middle layer is a 100 μm membrane, and the bottom layer contains the pneumatic mixers' and microvalves' air chambers. (b) Shows the photograph of the chip. Red ink denotes the mixer, green ink the valves, and blue ink the reaction wells and channels. The size of the chip is 8 × 4 cm.
