Scope of green nanotechnology towards amalgamation of green chemistry for cleaner environment: A review on synthesis and applications of green nanoparticles

Abstract Nanotechnology (NT) and its applications are contemporary and are outstripping the technology platform. It is indispensable in the fields of pharmaceuticals, nuclear energy, fuel and energy, electronics, bioengineering, etc. Aspects of green NPs (GNPs) in sundry fields have started conducing. The paper presents a pervasive review of the various methods of synthesizing GNPs, applications in various fields and limitations as well. The status quo of green nanotechnology (GNT) has been discussed comprehensively with a few recommendations to upscale the research level. Owing to the soaring urge of GNT, the paper unleashes the plethora of research being carried out in regards to this aspect, the leverage of GNT and its economic and environmental prospect. Venting the ways of synthesizing GNPs using plant extracts, plant wastes, bacteria, fungi, the review unfolds the bountiful fields it has been utilized in as well as asserts the reason for its adaptability with science and technology. The review presents the opportunities to use science, engineering and knowledge to design novel products benign to human and environment health. Challenges of GNT for transitioning from concept to reality have been detailed diligently.
