“…This method has become an interesting research subject because it has several advantages, such as reduced environmental impact and relatively low production costs. (Anis et al, 2023).. Turi leaves (Sesbania grandiflora) are one of the bioreductors that can synthesize silver nanoparticles (Das et al, 2013). This plant contains phytochemical compounds such as flavonoids, tannins, alkaloids, saponins, and terpenoids.…”

Research has been carried out on manufacturing liquid soap silver nanoparticles of Turi leaf extract. Ag nanoparticles have been used in various cosmetic and personal care products. This is because Ag nanoparticles have potential advantages such as increasing product stability, increasing absorption, and the ability to give special effects to the skin. From the physical properties test results, all soap formulas meet the standards set based on organoleptic, physical properties, pH, density, and viscosity. This research discusses the antibacterial activity of liquid soap. Formula 1 showed better antibacterial activity than formulas 2 and 3, with an inhibitory area reaching 23.84 mm. This can be explained by the fact that Formula 1 has a smaller particle size, namely 2161 nm. Formula 1 has the lowest AgNO3 concentration. The higher the concentration of AgNO3 used in the synthesis, the greater the amount of Ag+ that must be reduced, resulting in greater agglomeration and a larger size distribution of Ag nanoparticles.

The advancement in nanotechnology has completely revolutionized various fields, including pharmaceutical sciences, and streamlined the potential therapeutic of many diseases that endanger human life. The synthesis of green nanoparticles by biological processes is an aspect of the newly emerging scientific field known as "green nanotechnology". Due to their safe, eco-friendly, nontoxic nature, green synthesis tools are better suited to produce nanoparticles between 1 and 100 nm. Nanoformulation of different types of nanoparticles has been made possible by using green production techniques and commercially feasible novel precursors, such as seed extracts, algae, and fungi, that act as potent reducing, capping, and stabilizing agents. In addition to this, the biofunctionalization of nanoparticles has also broadened its horizon in the field of environmental remediation and various novel therapeutic innovations including wound healing, antimicrobial, anticancer, and nano biosensing. However, the major challenge pertaining to green nanotechnology is the agglomeration of nanoparticles that may alter the surface topology, which can affect biological physiology, thereby contributing to system toxicity. Therefore, a thorough grasp of nanoparticle toxicity and biocompatibility is required to harness the applications of nanotechnology in therapeutics.

The production of nanoparticles (NPs) using biological methods may lead to the enhancement of clean, non‐hazardous, and environmentally acceptable procedures. With this context, in the present study silver nanoparticles (AgNPs) were synthesized using the flower extract of Aerva lanata (A. lanata). The following techniques, including UV–visible spectroscopy, XRD, Scanning Electron Microscopy (SEM), and Fourier Transform Infrared Spectroscopy (FTIR), are used to study the crystalline nature, size, shape, and elemental composition of the biosynthesized AgNPs, and antimicrobial applications of the NPs also studied. In UV–visible spectroscopy results a strong absorbance peak at 425 nm confirmed the AgNPs. The SEM results confirmed the spherical shape of the NPs and their average size of 45.05 nm. X‐ray diffractometry XRD spectra confirmed the crystalline nature of the AgNPs. Against the DPPH (2,2‐diphenyl‐1‐picrylhydrazyl), nitric oxide and superoxide radicals, Alf‐AgNPs and ascorbic acid had significant scavenging effects at higher concentration of 250 μg/mL, exhibited 65.76 ± 0.41% and 86.42 ± 0.69%, 78.39 ± 0.49% and 72.72 ± 0.14% and 70.79 ± 0.87% and 72.79 ± 0.33% inhibition, respectively. As produced AgNPs had strong antibacterial and moderate antifungal activities against pathogenic test bacterial strains viz. Staphylococcus aureus (S. aureus), Bacillus subtilis (B. subtilis), Escherichia coli (E. coli), and Klebsiella pneumonia (K. pneumonia) with the maximum zone of inhibition 15 ± 1.07 mm, 12 ± 0.96 mm, 14 ± 1.05 mm, and 15 ± 2.54 mm, respectively at maximum (75 μg/mL) concentration of AgNPs, and the zone of inhibition of fungal strains Aspergillus fumigatus (A. fumigatus) (9 ± 0.67 mm) and Candida albicans (C. albicans) (7 ± 0.75 mm) at 75 μg/mL. It was eventually concluded that the biosynthesized Alf‐AgNPs showed promising antioxidant and antimicrobial agents with very low concentrations.
