Ferrocenium Ion Encapsulated Montmorillonite Clay as a Voltammetric Sensor for Distinguishing Amino Acids Glycine and Alanine

Abstract

Detection and determination of small bio-molecules and metal ions are of great importance for diagnosis of a number of diseases and understanding environmental pollution leading to extensive research on development of sensors. Among different sensors, electrochemical sensors are unique because of simplicity, low cost, easy maintenance and easy in vivo applications. Voltammetric sensor, one of the major constituents of electrochemical sensors, is essentially a surface modified working electrode (WE). The modifying agents may be surfactants, lipids, zeolites, clays etc. to name a few with or without a probe molecule. This paper embodies ferrocene encapsulated montmorillonite clay modified GC electrode as distinguishing voltammetric sensor between glycine and alanine. The redox currents of the modified electrode decrease to different extent on its interaction with glycine and alanine.
