In present study, a simple low cost method was used to prepare chitosan-nanosilica-graphene oxide(CS-NSi-GO) nanocomposite. Nanosilica and graphene oxide were synthesized from coconut huskash and chitosan was synthesized from shrimp shell. Nanosilica was synthesized from coconut huskash with alkaline extraction using sodium hydroxide followed by precipitation method using sulphuricacid. Graphene oxide was synthesized from the oxidative treatment of the raw material of coconuthusk ash. After the synthesis of silica, the carbonized graphite was collected and treated by modifiedHummer’s method. The CS-NSi-GO nanocomposite was prepared by condense polymerization method.Various analytical methods such as Fourier transform infrared (FTIR) spectroscopy, Fourier transformRaman (FT-Raman) spectroscopy, scanning electron microscopy (SEM), energy dispersive X-rayanalysis (EDAX) and transmission electron microscopy (TEM) were used to characterize theCS-NSi-GO nanocomposite. Eventually antibacterial, antifungal, antioxidant and cytotoxicity of theprepared nanocomposite were also evaluated.
