Structural and Morphological Characterization of Bio-templated Reduced Graphene Oxide and their Antibacterial Efficacy.

We would like to report the eco-friendly synthesis of reduced graphene oxide using aqueous extract of (rhizome), dried fruit and seed parts of and the whole shell part of by simple steam bath technique. The structural and morphological characteristics of prepared reduced graphene oxides were determined by UV-Visible spectroscopy, Fourier Transform Infra-Red spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM) and Raman spectroscopy. The Surface Plasmon Resonance at 260-280 nm ensured the reduced graphene oxide formation. The antibacterial efficacy of synthesized reduced graphene oxide was evaluated against both gram-positive and gram-negative pathogens such as and Among the selected samples mediated reduced graphene oxide showed excellent inhibition efficiency (27 and 28 mm) against and , respectively as compared to the standard Gentamycin (29 mm). showed significant inhibition of 22 mm and moderate inhibition of 18 mm against and , respectively The results suggest selected plants and chank shell-mediated reduced graphene oxide as potential antibacterial agents for various therapeutic applications.
