New membranes based on multicomponent and multifunctional hybrid nanofibers are finding potential application in biosensor, batteries etc. Recently, the preparation of composite nanofibers has become an important area of research. In the present work, new functional nanofibrous polymer membranes were prepared and used for biocatalytic application. In a typical approach, poly(vinylidene fluoride) nanofiberous membranes (PVdF-NFMs) were prepared via electrospinning. PVdF-NFMs were then loaded with functionalized silica and gold nanoparticles. Thus, new functional nanofibrous polymer membranes, PVdF-silica@AuNP-NFMs, were prepared. The surface morphology and structural aspects of PVdF-silica@AuNP-NFMs were investigated using scanning electron microscopy, Fourier transform infra-red spectroscopy and wide-angle x-ray diffraction analysis. PVdF-silica@AuNP-NFMs were immobilized with horseradish peroxidase (HRP) to generate the nanobiowebs.. The biocatalytic role of PVdF-silica@AuNP-NFMs/HRP nanobiowebs was evaluated towards the detection of hydrogen peroxide.
