Abstract:
1. A microfluidic system for assaying a plurality of cells, the microfluidic system comprising: a substrate defining a plane; and a plurality of microfluidic channels arranged in the substrate, each of said plurality of microfluidic channels comprising: further comprising: a medium disposed in said source channel, said cell chamber, and said sink channel; at least one cell provided within the medium of said cell chamber; an attractant provided within the medium of only said source channel, wherein the medium disposed in said sink channel is a blank medium; wherein fluid flow is restricted and diffusion is permitted between said cell chamber and said sink channel; and wherein fluid flow is restricted and diffusion is permitted between said cell chamber and said source channel; wherein a concentration gradient of the attractant is formed within said cell chamber between said source channel and said sink channel.
