Ultra-thin graphene has been receiving significance in the diverse sections of material science, owing to its exceptional physicochemical and thermo-mechanical characteristics. Currently, the fabrication of high-grade graphene in an economical target and green procedures area is a massive concern. Among the diverse techniques, chemical-mediated fabrication is believed to be the finest process since it is simple, scalable, and of low-cost; however, it involves noxious or hazardous chemical reducers for producing functional graphene-based Nanocomposites (NCs). Therefore, around the globe, scientists are endeavoring to adopt the bioinspired techniques to manufacture the functional reduced Graphene Oxide (rGO) and reduced Graphene Oxide-Metal/Metal Oxide (rGO-M/MO) NCs. Hence, keeping this issue in mind, the present review article summarize and integrates the current state of knowledge about the diverse bioinspired strategies developed to obtain rGO and rGO-M/MO NCs and their photocatalytic, antibacterial, and cytotoxic assessments.

由于其特殊的物理化学和热机械特性，超薄石墨烯在材料科学的各个领域都具有重要意义。目前，在经济目标和绿色程序领域制造高级石墨烯是一个巨大的问题。在各种技术中，化学介导的制造被认为是最好的工艺，因为它简单、可扩展且成本低。然而，它涉及用于生产功能性石墨烯纳米复合材料 (NC) 的有毒或有害化学还原剂。因此，在全球范围内，科学家们正在努力采用仿生技术来制造功能性还原氧化石墨烯 (rGO) 和还原氧化石墨烯-金属/金属氧化物 (rGO-M/MO) NCs。因此，牢记这个问题，
