Abstract
A technique is provided for incorporating pneumatic control in centrifugal microfluidics. The technique involves providing a chip controller that has pressurized fluid supply lines for coupling one or more pressurized chambers of the controller with ports of a microfluidic chip. At least part of the chip controller is mounted to a centrifuge for rotation with the chip. A flow control device is provided in each supply line for selectively controlling the pressurized fluid supply, and is electrically controlled. Bubble mixing, on and off-chip valving, and switching are demonstrated.
