New poly(vinylidene fluoride) based multi-functional (electroconductive, bioactive and catalytic) nano-biowebs were prepared through gamma radiation induced formation of silica and gold nanoparticles (Au NPs) within electrospun (poly vinylidene fluoride) nanofiberous membranes. The multifunctional membrane is designated as PVdF@silica/Au ESNFM. The morphology of PVdF@silica/Au ESNFM was examined by field emission scanning electron microscopy. The presence of Au particles was confirmed by energy dispersive x-ray analysis. The crystal structure of Au particles and the formation of silica were confirmed by X-ray diffraction analysis. The multi-functionalities (electroconductive, bioactive and catalytic) of the nano-webs were evaluated by cyclic voltammetry. Cytochrome c was immobilized to generate nano-bioweb (PVdF@silica/Au/cyt c ESNFM), which exhibited electrochemical responses to nitrite ions.
