In the present study, polyaniline-cadmium sulphide (PANI-CdS) nanocomposite material was synthesized by simple chemical polymerization method using FeCl3 as an oxidant. The prepared matrix was deposited as an active cladding material for the fabrication of cladding modified fiber optic intrinsic biosensor. The cladding modified material was used for the immobilization of biomolecules-enzyme-glucose oxidase (GOx) with the help of cross-linking technique. The nature of deposited nanocomposite material was confirmed using X-ray diffraction (XRD) analysis and field emission scanning electron microscopy (FE-SEM) techniques. Moreover, optical microscopy was used to observe the thin layer of deposited nanocomposite matrix on fiber optic sensing element. The prepared sensor can be used further for the detection of glucose solution of various concentrations. From the results, it has been found that PANI-CdS nanocomposite is biocompatible for the fixation of biomolecules on fiber optic sensing element. The results have been presented.
