    摘要: Microfluidic devices are fabricated by fabricating structures that are used to align elements that are to be attached to the devices or tools that are to be used in further fabrication steps on those devices. Elements to be attached include additional substrate layers, external sampling elements, e.g. capillaries, and the like. Preferred alignment structures include wells over which reservoirs are positioned, notches for use with alignment keys to align substrate layers or for receiving additional structural elements, and targets or guide holes for receiving tooling in further fabrication steps.

    摘要: The present invention provides a microfluidic system for fast, accurate and low cost electrophoretic analysis of materials in the fields of chemistry, biochemistry, biotechnology, molecular biology and numerous other fields. Light from periodically spaced regions along a channel in the microfluidic system are received by a photodetector. The intensity of light received by the photodetector is modulated by the movement of species bands through the channel under electrophoretic forces. By Fourier analysis, the velocity of each species band is determined and the identification of the species is made by its electrophoretic mobility in the channel.
