Electrochemical and optical evaluation of noble metal– and carbon–ITO hybrid optically transparent electrodes

Electrochemical and Optical Behavior of 8‐Hydroxypyrene‐1,3,6‐trisulfonic Acid at Optically Transparent Electrodes

“…While, the electrode material must be optically transparent for use in a spectroelectrochemical sensor, the electrochemical response of HPTS at the disk electrodes is improved over that at the ITO electrode. As shown by Zudans, et al [35], however, hybrid working electrodes, composed of a thin metal layer on an optically transparent support, acquire a surface material more appropriate for the electrolysis of the analyte with minimal reduction in the optical transparency of the electrode. The durability of these electrodes can be improved, due to improved adhesion, with the use of ITO as the base of the electrode instead of glass [36].…”

Quantitative Photoelectrochemical Detection of Biotin Conjugated CdSe/ZnS Quantum Dots on the Avidin Immobilized ITO Electrodes

“…solution of 0.1 M KCl. It is well known that CVof an electroactive probe such as Fe(CN) 3À 6 is a useful tool for testing the kinetic barrier of the interface [25,26] and thus the CV results could inform us about the formation of the monolayers and their packing densities. The voltammetric responses of the redox probe, Fe(CN) 3À 6 , both on the bare ITO and monolayer formed ITO electrodes (monolayer/ITO) were given in Figure 7a.…”

Reversible conformational change of cytochrome c at a modified gold electrode in methanol

“…The electrodes were sputtered (EmiTech 50 K550) with a thin layer of Au (6 nm) to make optically transparent electrodes (OTEs). 34 Self-assembled monolayers were created by modification of Au electrodes with a 2.5 mM mixed SAM solution (1:1 mixture of HS(CH 2 ) 10 COOH/HS(CH 2 ) 7 )OH) for 24 h. Cyt c (oxidised 55 form) was immobilised on to these electrodes by immersion of the electrodes in a 30 μM cyt c solution for 2-4 h. [35][36] Mixed solutions of buffer and methanol were prepared on a (v/v) basis. Sodium chloride (0.1 M) and lithium perchlorate (0.1 M) were used as the supporting electrolytes in buffer and 60 methanol solutions respectively.…”
