“…First of all, the collected Ipomoea aquatica leaves were separated from the petiole and then washed thoroughly with normal tap water followed by deionized water for three times ensuring the existence of no visible dust (15). The washed leaves were then dried naturally under the sun using a tray covered with aluminum foil paper for 5 days.…”

“…The dried leaf powder was collected and stored in an airtight box. After that, 1 g of fine leaf powder was mixed with 50 mL of deionized water in a glass beaker and heated on a hot plate at 80-100°C for 15 min (15). While heating the broth, the mixture was stirred occasionally with a clean glass rod.…”

“…The AgNPs containing cotton fibers exhibited high antibacterial (E. coli) activity (12)(13)(14). Although it is found that different shapes and sizes of AgNPs have a significant impact on the interaction with organisms, subcellular organelles, cells, and tissues (15). The study revealed that AgNPs also showed a significant amount of antiviral activities against respiratory pathogens, such as adenovirus, parainfluenza, influenza and especially respiratory syncytial virus (RSV) (16).…”

Metal nanoparticles have emerged as immensely desired materials because of their wide array of applications as antimicrobial agents, catalysts, nanomagnets, biosensors, environmental remediating agents, and so forth, but the problem lies with the traditional methods of their synthesis. These methods of synthesis are expensive, complex, less efficient, and hazardous to the environment. Thus, it calls for the development of greener and environmentally benign methods of their synthesis. Researchers worldwide have been vigorously trying to develop safer, simple, efficient, scalable, and eco-friendly methods to synthesize different metal nanoparticles. For this, various green protocols using diversified species of plants, algae, fungi, bacteria, and other microorganisms have been successfully developed.The purpose of this study is to give a detailed account of recent trends in synthesis and diverse applications of plant-based green metal nanoparticles. Plant-mediated synthesis of nanoparticles has emerged as the most soughtafter route since it is economical, convenient, rapid, reliable, stable, and can be used for large-scale productions. The plant-based nanoparticles have also exhibited a broad spectrum of applications in the fields of biomedicine, chemistry, physics, and environmental sciences. This study provides a comprehensive overview of the recent advances in plantmediated green synthesis of metal nanoparticles, their plausible synthetic mechanism, characterization techniques, and factors affecting their synthesis.This article also provides insights into the diverse applications exhibited by the nanoparticles covering their mechanistic aspects.

The green method is not only harmonious to our environment but saves time and is comparatively cheaper than other methods. The current study is aimed to synthesize the silver nanoparticles (AgNPs) using the green method by using the leaves of Loranthus pulverulentus Wall (LPW) which functioned as a reducing as well as capping agent. The synthesis of biogenic AgNPs was confirmed by UV-Vis spectroscopy (UV-Vis.), Scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), and Fourier transform infrared (FTIR). The absorbance maxima of the synthesized AgNPs were observed in the range of 405-435 nm. The SEM was used to find out the size and shape of the synthesized AgNPs, which revealed that the NPs were rectangular having sizes from 05 to 16 nm. XRD revealed that the synthesized NPs were crystalline and face-centered cubic (FCC). EDX analysis reflected the elemental composition of the synthesized product and showed that the percentage of silver = 92. FTIR was used to confirm the functional groups responsible for the reduction and stabilization of silver ions. It revealed that biomolecules present in plant extract were responsible for the reduction and stabilization of silver ions. The effect of temperature, pH, reaction time, silver nitrate concentration, and plant extract concentration on the synthesis of AgNPs were also investigated. The synthesized silver nanoparticles were tested against four bacterial strains which showed strong antibacterial activity. We conclude that biogenic silver nanoparticles could be used as antibacterial agents to treat various diseases. Research Highlights• Loranthus pulverulentus Wall leaf extract mediated synthesis of silver nanoparticles.
