Paper Abstract

Capillary electrophoresis arrays have been fabricated on planar glass substrates using photolithographic masking and chemical etching. The photolithographically defined channel patterns were first etched in a glass substrate, and then capillaries were formed by thermally bonding the etched substrate to a second glass slide. High-speed separations of restriction fragment digests were performed on these chips in under 1 minute. Multiple separations in the same channel demonstrated excellent reproducibility. Rapid genetic typing of short tandem repeats on the HUMTHO1 locus have also been performed. Finally, separations with single- base resolution have been successful, indicating that these microfabricated devices will also be useful for high-speed DNA sequencing.
