Research Abstract

Integration of electrochemical detection and/or reaction fields in a microchannel is one of important techniques for further development of "μTAS" or "lab-on-chip system", In this research, we developed novel methods to fabricate glass-substrate microchannel chips integrated with microelectrodes. The most important technology is bonding of channel and electrodes substrates without solution leakage. We established two methods, one is a method using sodium silicate as adhesive layer and another is thermal bonding. By using the methods, we succeed integration of metal electrodes such as Au, Pt, Ag, and so on, as well as semiconductor electrodes such as TiO_2 in microchannels. To check the electrochemical responses of the fabricated chips, we performed both cyclic voltammetry and chronoamperometry under solution flow conditions. Also, we calculated steady-state current from simulations by using a finite element method. The flow rate dependence of the experimentally obtained steady-state currents agreed very well with the calculated results, which indicated that the microelectrode worked well without solution leakage. As application of the electrode integrated microchannel, electrospectroscopic detection using thermal lens spectroscopy, electrochemical synthesis, and photocatalytic reactions were demonstrated.
