Development of natural based nanomaterial immense interest of researchers involved in eco-friendly biosynthesis of nanoparticles. This research set out to investigate the potential of Allium ampeloprasum leaves extract to synthesize silver nanoparticles (AgNPs), and evaluate their antifungal activity against some toxigenic strains of Aspergillus isolates. In order to achieve this, AgNPs were prepared using plant extracts at room temperature and the formation of AgNPs was visually detected after the color changed to dark brown within few minutes. The biosynthesized AgNPs were characterized using the UV-vis spectroscopy, which confirmed the formation of AgNPs with a maximum peak at 437 nm due to the Plasmon resonance. The main active reduction agents were detected by Fourier Transmission infrared spectroscopy (FTIR). Also, the nanoparticles were characterized using Scanning electron microscope (SEM). The antifungal activity of AgNPs was investigated by agar well diffusion method, which revealed inhibition zones of 8 mm, 10 mm, 11 mm, 11 mm and 14 mm against Aspergillus flavus 1, A. parasiticus, A. flavus 2, A. ochraceus, and A. niger. The minimum inhibition concentration (MIC) was determined using micro broth dilution method. MIC values of AgNPs ranged from 652 -2500 μg/ml. The fungi treated with AgNPs, were examined with (SEM), it was observed that the treated fungi were damaged. These results suggest that AgNPs have the potential to be used as an ideal eco-friendly approach to control toxigenic fungi.

Among different metallic nanoparticles, sliver nanoparticles (Ag NPs) are one of the most essential and fascinating nanomaterials. Importantly, among the metal based nanoparticles, Ag NPs play a key role in various fields such as biomedicine, biosensors, catalysis, pharmaceuticals, nanoscience and nanotechnology, particularly in nanomedicine. A main concern about the chemical synthesis of Ag NPs is the production of hazardous chemicals and toxic wastes. To overcome this problem, many research studies have been carried out on the green synthesis of Ag NPs using green sources such as plant extracts, microorganisms and some biopolymers without formation of hazardous wastes. Among green sources, plants could be remarkably valuable to exploring the biosynthesis of Ag NPs. In this review, the green synthesis of Ag‐based nanocatalysts such as Ag NPs, AgPd NPs, Au−Ag NPs, Ag/AgPd NPs, Ag/Cu NPs, Ag@AgCl NPs, Au−Ag@AgCl nanocomposite, Ag−Cr‐AC nanocomposite and Ag NPs immobilized on various supports such as Natrolite zeolite, bone, ZnO, seashell, hazelnut shell, almond shell, SnO2, perlite, ZrO2, TiO2, α‐Al2O3, CeO2, reduced graphene oxide (rGO), h‐Fe2O3@SiO2, and Fe3O4 using numerous plant extracts as reducing and stabilizing agents in the absence of hazardous surfactant and capping agents has been focused. This work describes the state of the art and future challenges in the biosynthesis of Ag‐based nanocatalysts. The fact about the application of living plants in metal nanoparticle (MNPs) industry is that it is a more economical and efficient biosynthesis biosynthetic procedure. In addition, the catalytic activities of the synthesized, Ag‐based recyclable nanocatalysts using various plant extracts in several chemical reactions such as oxidation, reduction, coupling, cycloaddition, cyanation, epoxidation, hydration, degradation and hydrogenation reactions have bben extensively discussed.

The aim of the study was to examine the influence of extraction method on the size, shape and morphology of synthesized silver nanoparticles (AgNPs). Silver nanoparticles were prepared by the aqueous and methanolic extracts of lemon balm. The properties of obtained nanoparticles were characterized by UV-Vis, SEM, XRD and FTIR techniques. The UV-Vis spectroscopy confirmed the formation of AgNPs by observing a distinct surface Plasmon resonance band around 450 nm. SEM images showed different shape, size and morphology of AgNPs using two different extracts types. AgNPs derived from the aqueous extract were rod-shaped with a diameter of 19 to 40 nm whereas spherical particles were synthesized by the methanolic extract found smaller with size distribution ranging from 13 to 35 nm. The XRD pattern indicated that AgNPs formed by the reduction of Ag + ions using methanolic extract of M. officinalis were crystal-like in nature. The functional groups of M. officinalis methanolic extract involved in synthesis and stabilization of AgNPs were investigated by FTIR. In addition, AgNPs-containing methanolic extract showed higher antioxidant activity. These particles exhibited remarkable antimicrobial activity against gram positive and negative bacteria and a fungus. The nanoparticles produced by the methanolic extract of the lemon balm showed antioxidant and antimicrobial activity. The production of silver nanoparticles using plant extract is rapid, low cost and eco-friendly. Therefore, green chemistry is a good alternative to industrial production of nanoparticles. Silver nanoparticles can be used as an antiseptic to sterilize the surrounding area and the hospital wastes.
