Abstract
Graphene oxide (GO) reduction, in particularly, the simple, cost effective and environmental benign microbial method attracts high over the other methods. Extracellular mediated actinobacterial reduction of nano graphene oxide is focused for the high purity and productivity of the product without any toxicity. In addition, Indian plant Cynodon dactylon also have an excellent ability to reduce the GO. Reduction of the nano-graphene oxide (nGO) to graphene nanoparticles (nRGO) was identified by visual colour change from brown to black. Further, the reduction of nGO into nRGO was confirmed through XRD pattern. Fig. 1 shows the disappearance of the peak at 2θ = 10° in the GO and formation of new broad peak at 2θ = 26° (JCPDS no. 411487) supports that the GO is completely reduced into graphene. The average Crystallite size of rGO is 8-10nm (Scherrer’s equation). Further the bioactivity of biological reduced nano graphene give the superior results compare than the chemically synthesized particles. Appropriate degradation as well as HAp layer formation supports the biological synthesis and suggests for the fruitful outcome for therapeutical applications
