ABSTRACT
The development of micro-and ultramicro (nano) analytical systems has been envisioned for some time, but only in recent years have such systems become a reality. The marrying of analytical science with microfabrication technologies, developed in the silicon electronics sector, have made it possible to manufacture or fabricate electrophoretic and chromatographic devices on an extremely small scale, thus creating the new fields of microtechnology and nanotechnology.
