Abstract
The present invention provides microfluidic sample processing systems and devices comprising a plurality chambers and channels in fluidic communication with a sample loading port, and methods of making and employing such systems and devices. Preferably, the systems and devices of the present invention are configured such that temperature changes in the chambers allows liquid sample in the sample loading port to be drawn into the channels.

23. A method of moving a fluid sample in a sample processing device, comprising:
-
a) increasing the temperature in a chamber in a sample processing device from a first temperature to a second temperature such that gas in said chamber expands; b) adding a liquid sample to a sample loading port in said sample processing device, and c) reducing the temperature in said chamber from said second temperature such that said gas contracts, wherein contraction of said gas causes at least a portion of said liquid sample to be drawn from said loading port into a channel in said sample processing device. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
