Multiple medicinal plants have been used to synthesize nanoparticles in this study, such as Silver, Gold, Iron, Zirconium, Platinum, Palladium and other metal oxides. This bioprocess of deriving nanoparticles from biotic components like plants, fungi, bacteria, etc is called Green Synthesis. A few examples of medicinal plants that can be used are Platanus orientalis, Papaver somniferum, Gloria superba, Azadirachta indica, Astragalus gummifer, among others. It is imperative to note that this technique not only has a plethora of applications but is also extremely eco-friendly, nontoxic and safe as it consumes very less energy in comparison to other methods. The basic principle behind extraction is collecting a plant part and mixing it with a metal salt solution. This solution is then stirred resulting in the production of nanoparticles and later characterized. They are classified as carbon-based, ceramic, metal, semiconductor, polymeric and lipid-based nanoparticles depending on their physical and chemical properties. Gold nanoparticle’s average size is highest among others at 400 nm. Cerium oxide has a melting point of 2613.15 K and Lanthanum oxide has a boiling point of 4473.15 K, which is very high. Platinum is the densest nanoparticle with a density of 21.45g/cm3. Zirconium has the largest surface area of 543m2/g. The areas of its applications vary from biomedical to physicochemical fields where natural products like flavonoids, alkaloids, saponins and tannins present in the above mentioned plant extracts have been used as potential precursors for nanoparticle production. Nanoparticles are pharmaceutically more efficient and are widely used in bio sensing, drug delivery etc.
