Polyaniline-CdS Quantum Dots Composite for Mediator Free Biosensing

Conducting polymers are known to be compatible with biological molecules and also have the quality to efficiently transfer the electric charges produced during the biochemical reactions through their conjugated backbone. In the past few years many conducting polymers have been used with the different prospects for biosensing applications. Among all these polymers, polyaniline is known to be semi-flexible rod and has been found to provide the efficient medium for electron transfer. The chemical and structural flexibility surrounding its amine nitrogen linkages for the immobilization of desired biomolecules has attracted much efforts towards the various applications in the field of biosensing due to its electrochemical, electronic, optical and electrooptical properties. Synthesis and functionalization of nanomaterials have aroused much interest due to large surface-to-volume ratio and the quantum confinement effect in semiconductor nanomaterials in which appropriate surface modification by stabilizers can remove localized surface-trap states resulting in increased quantum yield of the excitonic emission.
