Nanoparticles(NPs) are crucial in the development of future sustainable technologies for humanity and the environment. The synthesis of NPs by plants is a green chemistry approach that links nanotechnology with plant biotechnology. Metal ions are bioreduced using plant extracts to create NPs.This is environmentally friendly methodology for synthesising a diverse spectrum of metallic NPs such as metal/metal oxide nanomaterials, hybrid materials, and bio inspired materials. As a result, green synthesis is recognised as a significant technique for reducing the harmful consequences associated with standard methods of synthesis for NPs routinely used in laboratories and industry. We summarised the key processes and mechanisms of biosynthesis methodologies, particularly for metal and metal oxide NPs utilising natural extracts in this study. The stability/toxicity of NPs, as well as the surface engineering techniques used to achieve biocompatibility, are also covered. Finally, we discussed environmental remediation applications of such synthesised compounds in terms of antibacterial activity, catalytic activity, pollutant dye removal, and heavy metal ion sensing.
