Purdue Microfluidic Device

Most microfluidics “chips” are made of glass or plastic with etched channels, though several research groups have been experimenting with hydrophobic-coated paper chips upon which lasers burn the channels.  Instead of using an electrical current or pumps to move the fluid, paper simply wicks it.  The advantage is the low cost and enormous usefulness in point of care situations.   MORE
