“…The selected area electron diffraction (SAED) pattern of the as-prepared silver nanoparticles is shown in Figure 2D and confirms the nanoparticles' crystalline nature and that the observed structure is silver. 3,66 The size measured by the DLS was 22.1 nm ± 2.3 nm, which indicates that the organic coating's size is approximately 16.9 nm, 70 which is consistent with the 71 and S. muricatum (20-80 nm) 72 that used microwave-assisted synthesis, the observed size is significantly smaller. The analysis of the diffraction pattern (XRD) in Figure 2E shows the observed peaks at angles 2F.…”

Purpose The importance of studying polyphenolic compounds as natural antioxidants has encouraged the search for new methods of analysis that are quick and simple. The synthesis of silver nanoparticles (AgNPs) using plant extracts has been presented as an alternative to determine the total polyphenolic content and its antioxidant activity. Methods In this study, aqueous leaf extract of Solanum mammosum , a species of plant endemic to South America, was used to produce AgNPs. The technique of oxygen radical absorption capacity using fluorescein (ORAC-FL) was used to measure antioxidant activity. The oxidation of the 2´,7´-dichlorodihydrofluorescein diacetate (DCFH 2 -DA) as fluorescent probe was used to measure cellular antioxidant activity (CAA). Electrochemical behavior was also examined using differential pulse voltammetry (DPV) and cyclic voltammetry (CV). Total polyphenolic content (TPH) was analyzed using the Folin-Ciocalteu method, and the major polyphenolic compound was analyzed by high performance liquid chromatography with diode array detector (HPLC/DAD). Finally, a microbial analysis was conducted using Escherichia coli and Bacillus sp. Results The average size of nanoparticles was 5.2 ± 2.3 nm measured by high-resolution transmission electron microscopy (HR-TEM). The antioxidant activity measured by ORAC-FL in the extract and nanoparticles were 3944 ± 112 and 637.5 ± 14.8 µM ET/g of sample, respectively. Cellular antioxidant activity was 14.7 ± 0.2 for the aqueous extract and 12.5 ± 0.2 for the nanoparticles. The electrochemical index (EI) was 402 μA/V for the extract and 324 μA/V for the nanoparticles. Total polyphenolic content was 826.6 ± 20.9 and 139.7 ± 20.9 mg EGA/100 g of sample. Gallic acid was the main polyphenolic compound present in the leaf extract. Microbiological analysis revealed that although leaf extract was not toxic for Escherichia coli and Bacillus sp., minor toxic activity for AgNPs was detected for both strains. Conclusion It is concluded that the aqueous extract of the leaves of S. mammosum contains nontoxic antioxidant compounds capable of producing AgNPs. The methods using AgNPs can be used as a fast analytical tool to monitor the presence of water-soluble polyphenolic compounds from plant origin. Analysis and detection of new antioxidants from plant extracts may be potentially applicable in biomedicine.

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.
