Development and Use of the Broadband Electroactive Integrated Optical Waveguide to Study New Chemical Systems Through Ultrasensitive Spectroelectrochemistry

摘要

Two recent developments in our laboratories have led to unprecedented advances in optical waveguiding platforms.These technological advances have stemmed from the development of:1)the electroactive integrated optical waveguide (EA-IOW)and 2)the broadband coupled IOW.The first advance was in the creation of an electroactive waveguide structure,called the EA-IOW,achieved by deposition of a transparent,conductive indium tin oxide electrode material,allowing for simultaneous collection of electrochemical response and spectrometric response of surface bound redox active molecules.This is a "first generation"device which has been used to measure spectroelectrochemical responses of surface adsorbed species at an unprecedented level of sensitivity.
