Green Synthesis of Metallic Nanoparticles - An Ecofriendly Approach
Nanotechnology is one of the most popular fields of research in material sciences. Because of its unique properties like extremely small size and large surface area to volume ratio, the synthesis of nanoparticles is rising significantly throughout the research world. Production of NPs by using green process has gained the attention of many researchers and several studies have been carried out in current years because of its ease of use and environmental friendliness.The plant extracts were used as reducing and stabilizing factors for the synthesis of nanoparticles as it shows several bioactivities and hence is used as efficient delivery vehiclesCharacterization techniques such as FTIR, Ultraviolet-Visible spectroscopy, SEM and HPLC, XRD and other is important to confirm the biosynthesis of NPs before use. Metallic nanoparticles are being used for more than thousands of years. They vary in term of sizes, shapes, solubilities and long-term stability as they are made up of various inorganic oxides. Due to their antimicrobial, anti-inflammatory, antioxidant or anti-cancerous activities, metal-based nanoparticles in biomedical and pharmacological industries for the diagnosis and treatment of several diseases. Therefore, producing metal nanoparticles from plants and plant extracts have several advantages over other methods of NPs production as it is simple, cost effective, easy, environmentally friendly and gives large scale production. It is simple to use green NP generation methods, and they are also beneficial from an economic point of view.
