Fig 4. A schematic view of the four-well chip, the device used for the four-droplet network.
(a) A four-droplet network for Negative-AND operation. Input (1, 0) was selected as an example. The input DNA strands were injected into the input droplets and the CDNA strands were prepared in the operation droplet. (b) An overall view of the 4WC. The electrodes in the wells were connected to a patch-clamp amplifier. (c) The wiring to the four wells. The electrodes were embedded on the bottom of the wells.
