In this paper we describe silicon miniaturized electrochemical cells composed by three planar microelectrodes. The cells are embedded on PCB board for the electrical driving and reading. The microelectrodes are produced using the VLSI technology, in particular the counter and reference are made of gold, while the working microelectrodes was manufactured in platinum and nickel depending the application...
An effective electrode modification strategy, integrated in a miniaturized silicon biosensor, was investigated for the rapid and sensitive electrochemical detection of low amount of DNA without PCR step. The miniaturized biosensor here presented is composed of three planar microelectrodes for electrochemical transduction of hybridized DNA target on working electrode, the hybridization is probed by...
