| abstract |
A novel method and device for transporting and/or monitoring a fluid in a multi-port device 400, 800, 1000 used in a microfluidic system is provided. The multi-port device includes a substrate having a novel channel configuration. A first channel region 413 having a first port and a second port for transporting fluid therebetween is defined in the substrate. A second channel region 421 having a first port and a second port for applying electric current for heating fluid or for monitoring a fluid parameter therebetween is also defined in the substrate. In some embodiments, the first channel intersects 407 with the second channel. The heating or monitoring aspect of the invention can be used with a variety of biological reactions such as PCR, LCR, and others. |
