Abstract
Nanocomposites assembled with TiO2 and graphene were synthesised under solvent free conditions. The calcinated nanocomposites have been characterized by PXRD, SEM-EDAX, HRTEM and Nitrogen adsorption-desorption techniques. Nanotitania was found to be formed in anatase phase with larger surface area (268.2 m2g-1) and with increase in graphene content, the absorbance increased towards visible region. Their biological applicability has been evaluated by examining their anti-bacterial activity against E. coli (ATCC29181), S. aurues (ATCC6538) and their anti-fungal activity against C. albicans, C. rugosa (ATCC10231) organisms. It has been observed that the biological activity has increased with increase in % graphene from 0.1 to 0.5 and showed a steady decrease with 1.0 % graphene. Compared, to the anti-fungal activity, anti-bacterial activity was identified to be major in the present studies.
