A comprehensive review on green nanomaterials using biological systems: Recent perception and their future applications

Abstract

Over the last few years, nanotechnology is increasingly developing in scientific sector, which has attracted a great deal of interest because of its abundant applications in almost all the areas. In recent times, green nano technology is a relative and multidisciplinary field that has emerged as a rapidly developing research area. This is serving as an important technique that spotlight on making the procedure which is clean, safe and in particular environtmentally friendly, in a gap with the currently employed methods such as chemical and physical methods for nanosynthesis. The present review recaps the existing knowledge on various biogenic synthesis methods relying on bacteria, fungi, yeast, algae, viruses and on using biomolecules. The green nanosynthesis refers to the employment of reducing and stabilizing agents from plants and other natural resources, to fabricate nanomaterials. The green synthesis method does not engage the use of exceedingly venomous chemicals or elevated energy inputs during the synthesis. Nanoparticles (NPs) with distinct shapes, sizes and bioactivity can be produced from the variations in the bio-reducing agents employed for nanosynthesis. Hence, this review article summarizes the present information regarding the biological methods which are employed to fabricate greener, safer, and environmentally sustainable nanosynthesis routes. This review mainly highlights the wide-scale fabrication of NPs via green synthesis for biomedical and agricultural applications.
