Abstract
In this study, we used the grinding modification approach to modify the carbon paste electrode (CPE) from an environmentally friendly catalyst (L-serine). L-serine(L-s) is shown to be an effective electrocatalytic at the modified CPE (MCPE) interface for detecting dopamine (DA). L-sMCPE showed excellent activity to detect DA in commercial injection samples with a recovery range of 98.9 to 100.5%. Theoretical studies were used to understand the electrocatalysis of L-serine at the atomic level using frontier molecular orbitals and analytical Fukui assay. The amine group of L-serine works as an extra oxidation site (cause for enhanced reduction peak DA) and a carboxylic acid group (reason for enhanced oxidation peak DA) at the L-sMCPE interface, according to our theoretical findings. Improvements to these processes might have a big influence on knowledge of the electrode interface for sensing applications.
