Abstract
A method is provided of controlling communication between multiple ports in a microfluidic device. The method includes the step of providing a channel network in a microfluidic device. The channel network including a first channel having a first input port and an output port. The first channel is filled with a fluid and a first output droplet is deposited on the output port. The first output droplet has a radius of curvature. The first output droplet flows toward the first input port in response to placement of a first input droplet having a radius of curvature greater than the radius of curvature of the first output droplet on the first input port. The first input droplet flows toward the output port in response to the first input droplet having a radius of curvature less than the radius of curvature of first output droplet.
