Electrochemistry Behavior of Ag/TiO2 Nanobelts and its Potential Applications on Mercapto Proteins Detection

Abstract

Glassy carbon electrodes (GCEs) were modified by TiO2 and Ag/TiO2 heterostructured nanobelts, respectively. The corresponding electrodes were marked as TiO2/GCE and Ag/TiO2/GCE, respectively. The electrochemical properties of Ag/TiO2/GCE had good and stable electrochemical characteristics in phosphate buffer solution (PBS), and it can be applied to the trace detection of L-cysteine. When the concentration of L-cysteine is in 10-7 order of magnitude, it is more sensitive.
