Study on adsorption and desorption process of thiol-modified probe on gold electrodes using cyclic voltammetric method
Abstract
In this paper, we study the electrochemical properties of self-assembling monolayers (SAM) created by the adsorption and desorption of the alkanethiol at the gold nanowires (AuNW) electrode surface by using the CV method. The analysis results show that the effectiveness of the desorption process reached over 90 %. The adoption of a negative voltage caused SAM desorption which resulted in the separation of SAM from the electrode. Our purpose is to reuse gold electrodes after they have been functionalized by SAM. Besides, results of this study also help to eliminate the electrochemical methods that make SAM eluted and therefore protect samples more effectively in the survey process
