Abstract:
In some embodiments of the present invention, the buried silicon oxide technology is employed in the fabrication of fluid channels, particularly nanochannels. For example, a fluid channel can be made in a buried silicon oxide layer by etching the buried oxide layer with a method that selectively removes silicon oxide but not silicon. Thus, one dimension of the resulting fluid channel is limited by the thickness of the buried oxide layer. It is possible to manufacture a very thin buried oxide layer with great precision, thus a nanochannel can be fabricated in a controlled manner. Moreover, in addition to buried oxide, any pairs of substances with a high etch ratio with respect to each other can be used in the same way. Further provided are the fluid channels, apparatuses, devices and systems comprising the fluid channels, and uses thereof.
Abstract:
A microanalytical device is provided for conducting multiple chemical and/or biochemical reactions and analyzing multiple sample fluids in parallel using minute volumes of reaction or sample fluid. The devices comprises a well plate with an integrated microfluidic system containing processing compartments such as microcavities, microchannels and the like, that are in fluid communication with electrospray emitters. The novel microanalytical device can be used in a variety of chemical and biochemical contexts, including mass spectroscopy, chromatographic, electrophoretic and electrochromatographic separations, screening and diagnostics, and chemical and biochemical synthesis. The devices may be formed from a material that is thermally and chemically stable and resistant to biofouling, significantly reducing electroosmotic flow and unwanted adsorption of solute.
