Pre-post electron transfer regioselectivity at glycine modified graphene electrode interface for voltammetric sensing applications

In the last few years, glycine (GL) showed good experimental evidence as an electron transfer (ET) mediator at carbon (in particular graphene (GR)) interface. However, ET properties of GL modified GR interface are still not known completely. These can be achieved using density functional theory-based models. Modelling electrode interfaces is essential in electroanalytical chemistry to get insights into their electronic and redox properties. Here we have modelled find out its interfacial Conceptual theory concepts like frontier molecular orbital (FMO) analytical Fukui functions were utilized predict sites on surface. It shown that glycine-modified interface, amine groups act additional oxidation carboxylic acid reduction sites. Therefore, acts graphene-based The obtained results well supported by previously published reports.
