Molecularly imprinted polymer-based electrochemical sensor for the determination of endocrine disruptor bisphenol-A in bovine milk

•Molecularly imprinted polymer sensor for bisphenol-A was developed.•Molecular interactions of Bisphenol-A on polymer was computationally analysed.•Bisphenol-A imprinted polypyrrole electrochemically synthesised on the reduced graphene oxide film.•Bisphenol-A detected in bovine milk and water samples stored from polycarbonate bottles.
