The electrochemical characteristics of blue copper protein monolayers on gold

Abstract:

Site-specifically engineered disulphide or surface cysteine residues have been introduced into two blue copper proteins, Pseudomonas aeruginosa azurin and Populus nigra plastocyanin, in order to facilitate protein chemisorption on gold electrodes. The subsequently formed well-defined protein monolayers gave rise to robust electrochemical responses and electron transfer rates comparable to those observed at modified electrode surfaces. Proximal probe characterisation confirms the presence, at ...
