Microchips are one of the most promising analytical platforms due to the great advantages with respect to conventional bench-top equipment. Microfluidic devices are able to offer custom design, high throughput, sensitivity, selectivity and portability. In order to achieve a real point-of-care measurement device, simple instrumentation has to be integrated to drive the injection and separation. Electrochemical detection (ECD) methods have been widely applied for the detection of bio-compounds because they are less susceptible to decreases in signal magnitude during miniaturization and are already portable and inexpensive. For these reasons, we are very interested in studying the design, operation and biological applications of microchips and capillary electrophoresis. In addition, we are also interested in the rational design of biosensors.
