Abstract

Polymers are excellent host materials for nanoparticles of metals and semiconductors. PVA-Ag-Cu nanocomposite was synthesized from chemical reduction, whereas PANI-Ag-Cu nanocomposite was synthesized by chemical oxidative polymerization. PVA-Ag-Cu and PANI- Ag-Cu thin films were deposited on the glass substrate by spin coating technique. The films were characterized by using XRD and AFM. The sensitivity of the samples was analyzed by I-V measurement. The peaks in XRD patterns confirm the presence of Ag-Cu nanoparticles in face centered cubic structure. AFM images show the roughness of PVA-Ag-Cu and PANI-Ag-Cu increased as Ag concentration decreased and Cu concentration increased. I-V measurements indicate that the change in the current of the films increases with the presence of E. coli. The sensitivity on E. coli increases for PVA-Ag-Cu and PANI-Ag-Cu thin films with high concentration of Cu.
