Abstract

The adsorption behavior of amino acids, such as L_cysteine, histidine and arginine at gold_quartz crystal microbalance (Au_QCM) was investigated. The adsorption quantity of cysteine is more appreciable than others because of the stronger interaction between its thiol group and the gold electrode surface. The electron_transfer process of superoxide dismutase(SOD) in presence of cysteine at Au_QCM has also been studied using the electrochemical quartz crystal microbalance (EQCM) technique which reveals clearly the quasi_reversible electron_transfer process accompanied by the frequency shift cycle. The reversible adsorption and disorption processes are discussed.
