dc.description.abstractRemarkable progress has been achieved in both applied and fundamental scientific newlineinvestigations on graphene and graphene-based nanomaterials due to its unusual catalytic, newlinemechanical, electronic and electrical properties. The potentials of Graphene/RGO should newlinebe thoroughly evaluated for health and environmental impacts. In this context, biological newlineproperties and toxicity of Graphene/RGO based hybrid nanomaterials gaining the newlineimportance. There are only few reports on these materials when compared to other carbon newlinebased nanomaterials, such as carbon nanotubes (CNT s) and fullerenes. newlineThe present thesis makes an effort to develop phytochemicals assisted synthesis of newlinegraphene based metal/metal oxide nanoparticles with their potential application in newlinebiomedical applications as antibacterial, antimicrobial and antioxidant agent. The literature newlinesurvey carried out revealed that there is scope for developing Reduced Graphite Oxide newlineAg/Cu2O hybrid nanomaterials through phytochemical assisted reduction method using newlineAleo vera plant/Marigold Flower extract. newlineReduced Graphite Oxide Ag/Cu2O hybrid nanomaterials were synthesized using newlineplant extract in a simple solution process. The detailed study on microstructure and newlinemorphology of prepared samples by FESEM and TEM revealed that hybrid nanomaterials newlinewhere Ag/Cu2O nanoparticles are decorated on the surface of the RGO. The crystal newlinestructure and phase analysis and indexing the pattern obtained by XRD showed that newlineAg/Cu2O nanoparticles without any impurity was obtained. Investigation with UV-visible newlineand FTIR spectroscopy methods showed optical properties hybrid nanomaterials and the newlinefurther confirmation for the formation of hybrid nanomaterials and their surface functional newlinenature. newlineRGO-Ag/Cu2O nanocomposites prepared using extracts of Aloe vera and Marigold newlinewere used to test both antibacterial and antifungal effect. Antibacterial activity was newlineevaluated using E.coli, B.subtilis and X.vesicatoria organisms by zone of Inhibition and newlinebroth dilution methods. Amongst whic
