Platinum nanoparticles (PtNPs) have a variety of beneficial applications in the domains of medicine and the environment, making them an exciting and fascinating research topic. The goal of current research is to provide a route in order to synthesise platinum nanoparticles that is environmentally sustainable as well as cost-effective. Physical-chemical approaches of Pt NP synthesis have been improved by bio-fabrication protocols based on bacteria, fungi, and plant extract. In comparison to other biological synthetic approaches like bacteria and fungi, this review article addresses the methods in which platinum nanoparticles can be synthesised by various plant extracts as this method does not involve any time-consuming culturing and preservation. Furthermore, platinum nanoparticles produced from plant extract are more stable, precise and efficient and can easily modify in various shapes and sizes. Extracts of various plants like P. salicifolium, Tragia involucrata leaf extract (Ti-PtNPs), almond skin extract, zahidi dates, Atriplex halimus leaf, Prosopis farcta fruit, Phoenix dactylifera L.'s Anbara fruit Rumex dentatus seeds have been successfully employed for the synthesis of platinum nanoparticles.
