Abstract Background Scientists created a new area known as "green nanotechnology" by combining the concept of sustainability with nanotechnology. Its goal is to eliminate the use of chemicals in nanoparticle manufacturing by replacing them with plant-based materials. Green synthesis is promoted as the best alternative to the traditional method of nanoparticle synthesis in this new domain. Plants that constitute a major portion of our biodiversity are embraced with inherent potentiality to be transformed as miracle medicine due to its phytochemicals. These phytochemicals efficiently replace the classical wet chemical ingredients involved in nanoparticle synthesis by upgrading to greener method for its synthesis. By incorporating plant-based sources as the chief ingredient of nanoparticle synthesis, we are able to reduce the hazards of greenhouse gas emissions and enlighten the insights of our scientific community with nanotechnology for green innovation. Hence, this review simultaneously aims at promoting plant extracts as the most efficient as well as renewable recipe for green synthesis of silver nanoparticles and preparing earth for a greener tomorrow. Methodology Scientific articles and publications were selected from reputed journals and sorted out with pertinent keywords of this review. Electronic sources like Google Scholar, PubMed, Research Gate, Science Direct, Wiley Online Library, Web of Science and Scopus were searched for potential articles and recent breakthroughs published in the area of silver nanoparticle synthesis via green chemistry and biological methods using plant extracts. Scientific names of medicinal plants were checked using botanical databases like Plant List and International Plant Names Index. Conclusion This review pinpoints on empowering better life on earth by protecting it from hazardous effects of conventional nanotechnological production through replacing the former with sustainable green synthesis approach. Ergo, it outlines that by incorporating plant-based sources as the chief ingredient of nanoparticle synthesis, we are able to reduce the hazards of greenhouse gas emissions in turn by slowing down increasing climate change disasters globally and enlighten the insights of our scientific community with nanotechnology for green innovation.

The development of nanomaterials often relies on wet-chemical syntheses performed in reflux-setups using round-bottom-flasks. An alternative approach to synthesize nanomaterials is here presented that uses glass tubes designed for NMR analysis as reactors. This approach uses less solvent, uses less energy, generates less waste, provides safer conditions, is less prone to contamination and is compatible with high throughput screening. The benefits of this approach are illustrated by an in breadth study with the synthesis of gold, iridium, osmium and copper sulfide nanoparticles.

Abstract: Nanotechnology is a creating part of drug sciences wherein the particles reach out in nanosizes and end up being more responsive when appeared differently in relation to their novel partners. Nanoparticle synthesis utilizing microorganisms and plants by green synthesis innovation is naturally protected, cost-effective, and environment-friendly. This development is especially repaying similarly as diminishing the noxious quality brought about by the ordinarily coordinated Nanoparticles. The compelling conveyance of medications and tissue designing using nanotechnology displayed fundamental commitments in translational examination identified with the drug items and their applications. Nanotechnology related to science leads to a high level space of nanobiotechnology that includes living substances of both prokaryotic and eukaryotic beginning like algae, cyanobacteria, actinomycetes, bacteria, viruses, yeasts, fungi, and plants. This review makes a brief introduction of environment friendly Nanoparticles and their implementations.

With the growing awareness for the need of sustainable environment, the importance of synthesizing and the application of green nanoparticles has gained special focus. Among various metal nanoparticles, silver nanoparticles (AgNPs) have gain significant attention. AgNPs are synthesized conventionally by physical and chemical methods using chemicals such as reducing agents, which are hazardous to environment due to their toxic properties, provoking a serious concern to create and develop environment friendly methods. Thus, biological alternatives are emerging to fill gaps, such as green syntheses that use biological molecules taken from plant sources in the form of extracts, which have shown to be superior to chemical and physical approaches. These biological molecules derived from plants are assembled in a highly regulated manner to make them suitable for metal nanoparticle synthesis. The current review outlines the wide plant diversity that may be used to prepare a rapid and single-step procedure with a green path over the traditional ones, as well as their antifungal activity.

Recently, nontoxic origin-mediated synthesis of copper oxide nanoparticles acquires further recognition because of the key role of bioapplications. The plant Cissus quadrangularis is one most prominent herbs used in the treatment of diabetes, asthma, tissue regeneration, etc. In this study, we tested the process of copper oxide nanoparticle synthesis and their role in many functions from Cissus quadrangularis. The synthesis of copper oxide nanoparticles uses plant extract and characterization by X-ray diffraction, thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FT-IR), atomic force microscope (AFM), and scanning electron microscope (SEM). The synthesized nanoparticles were analyzed for their biomedical applications such as antibacterial, antifungal, antioxidant, antidiabetic, and anti-inflammatory activity and antiproteinase action. The results show that the C. quadrangularis plant-mediated nanoparticles may be used in many biomedical applications related to arthritis, diabetes, and the production of various antimicrobial products in the future.
