Abstract: A microfluidic device includes a semiconductor microchip including fluid active circuitry and transistor circuitry, wherein the transistor circuitry provides onboard logic at the semiconductor microchip to control the fluid active circuitry. The microfluidic device further includes a microfluidic chamber fluidly coupled to an inlet port and an outlet port, wherein the microfluidic chamber is defined in part by a microchip surface with the active circuitry positioned to interact with fluid introduced into the microfluidic chamber and partially defined by an enclosing surface. The microchip surface, the enclosing surface, or both include a chemically-modified microfluidic chamber surface that is selectively interactive with a target component of the fluid.
