Recognition of biomolecules using gold-polymer composites: metal nanoparticles play the role of the catalyst

摘要

A facile synthesis route has been described for the preparation of gold-polymer supramolecular architecture with interesting physical properties and potential applications. The supramolecular material was investigated by microscopic, optical and surface characterization techniques. The composite architecture shows good colorimetric and voltammetric sensor application for the detection of biomolecules, where the gold nanoparticles play the role of a catalyst for both the applications in two different mechanistic pathways.
