SYNTHESIS OF METAL NANOPARTICLES AND THEIR USE IN ELECTROCHEMICAL BIOSENSORS FOR THE DETECTION OF MICROBES
One of the important applications of electrochemical biosensor is their use in the detection of microorganisms (bacteria, virus, spores, fungi, pathogens etc. present in air, water, food, soil etc. Nanoparticles of different metals were synthesized for this purpose by the Coprecipitation method. Characterization of metal nanoparticles was carried out by XRD, FTIR, TEM and UVVisible spectroscopic techniques. Nanoparticles based working electrode was fabricated for this purpose and then combined with two other electrodes i.e. Ag/AgCl reference and a platinum counter electrode to study its application as electrochemical biosensors in the detection of microbes present in analyte.
