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.
