We would like to report the eco-friendly synthesis of reduced graphene oxide using aqueous extract of Acorus calamus (rhizome), dried fruit and seed parts of Terminalia bellirica, Helicteres isora and Quercus infectoria and the whole shell part of Turbinella pyrum 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 Staphylococcus aureus, Bacillus subtilis, Salmonella paratyphi and Escherichia coli. Among the selected samples Quercus infectoria mediated reduced graphene oxide showed excellent inhibition efficiency (27 and 28 mm) against Escherichia coli and Staphylococcus aureus, respectively as compared to the standard Gentamycin (29 mm). Quercus infectoria showed significant inhibition of 22 mm and moderate inhibition of 18 mm against Bacillus subtilis and Salmonella paratyphi, respectively. The results suggest selected plants and chank shell-mediated reduced graphene oxide as potential antibacterial agents for various therapeutic applications.
