Modification of carbon silk screen printed electrodes for use as sensors comprises controlled oxidation to enhance adsorption of streptavidin on the electrode surface

摘要

The modification of carbon silk screen printed electrodes for use as sensors consists of application of a constant oxidation potential in an acid medium to increase the electrode's surface adsorption capacity. Then streptavidin is adsorbed on the surface at a constant below-ambient temperature, for use in e.g. immune sensors and gene sensors.
