Selective Electrochemical Detection of Bisphenol A using Molecular Imprinted Polymer Nanocomposite

Abstract

Bisphenol A is the most common endocrine disrupting chemical found in environment and its human exposure leads to variety of health issues. Thus detection and removal of bisphenol A from industrial waste/soil/drinking water are critical to minimize human consumption. Here we report molecular imprinted nanocomposite for selective electrochemical detection of bisphenol A. The nanocomposite has covalently connected polyacrylate, β-cyclodextrin and reduced graphene oxide components with the molecular imprints of bisphenol A for its selective capture via host-guest complexation with β-cyclodextrin. Bisphenol A can be selectively detected in presence of various bisphenol A analogues via electrochemical approach where reduced graphene oxide component induces electrocatalysis. Linear concentration range of bisphenol A detection is in the range of 0.02-1.0 μM with limit of detection (LOD) of 8 nM. This approach has been used for the detection of bisphenol A in contaminated water and may be extended for detection of bisphenol A in other natural contaminants.
