20080226504 | PUMP UNIT AND CENTRIFUGAL MICROFLUIDIC SYSTEM HAVING THE SAME - Provided are a pump unit and a centrifugal microfluidic system including the pump unit. The pump unit includes a gas generating agent. The gas generating agent includes a plurality of heating particles generating heat by absorbing energy and one of a sublimation material, azide, and azo compound mixed with the heating particles. When energy is supplied to the gas generating agent, the gas generating agent generates gas due to heat emitted from the heating particles to increase an air pressure around the gas generation agent so that the fluid is moved by the increased air pressure. | 09-18-2008 |
