Study of Magnetic Iron Oxide Nanoparticles and their Application as a Glucose Biosensor

Abstract

Fe3O4 nanoparticles have been used as a drug delivery in medical, biosensing and bioimaging. Due to quick response time it is used for biosensing. In this study, Fe3O4 nanoparticles were prepared by Coprecipitation method with variation in stirring time. The prepared material was characterized by XRD, SEM and FTIR. Single phase composite material examined by XRD and average crystallite size found to be 60nm. SEM images shows the proposed material is homogeneous and dense. The working electrode was prepared successfully using glassy carbon. The electrochemical measurement is performed for different concentration of glucose. Increment in glucose concentration gives the linear response in form of higher potential.
