Manufacturing of metal and metal oxide nanoparticles (M/MO NPs) in large quantities needed a strong reliable, sustainable, and eco-friendly protocol. Present work represents on biogenic approaches to fabricate green nanoparticles using green technology. The fabrications of M/MO NPs using natural bio-resources were engaged by means of alternative technique in place of conventional methods. These methods are naturally benign, straightforward, economical, and renewed technology; they does not content harmful chemicals, zero contaminants, and eco-friendly. The extracts from the biogenic resources are widely accepted owing to its capability to minimise and control the size and shape of metal and metal oxides NPs because of different structure directing agents, usually bioorganic phyto-chemicals. In this present review, we have summarized fabrication of different NPs like silver, gold, copper oxide, cobalt oxide, titanium oxide, cerium oxide, bismuth oxide, zinc oxide and nickel oxide nanoparticles using natural resources. The challenges, limiting factors and future directions of the bioinspired synthesis of metal/metal oxide NPs are also highlighted in this review. Moreover, biogenic materials has explored for further environmental remediation in terms of photocatalytic activity, elimination of organic waste, and antibacterial, antioxidant assay, and protein-metal complexes binding affinities by molecular docking. © 2022 The Author(s)
