“…Intracellular synthesis method is suitable for formation of composite films. However, in extracellular synthesis method, the immobilization of metal ions in suitable carrier or support is achieved [39]. The key components, metabolites and the enzymes present in the fungi have great importance and they are secreted by the fungal cells to convert toxic matters into non-toxic matters; these substances might be also involved in the synthesis process of nanoparticles [40].…”

Nanotechnology mainly involves the fabrication, manipulation, and utilization of materials in nano size (materials having size less than a micron to that of individual atoms). However, nanoparticles can be synthesized by several chemical and physical approaches; now, it is also possible to integrate the use of biological entities. In recent years, mycogenesis of nanoparticles is considered as a prominent way where fungi can be used for the production of nanostructures with desirable shape and size intracellularly or extracellularly. Several researchers have reported that NADH-dependent nitrate reductase enzyme plays an important role in transformation of metal ions into metal nanoparticles. The size and shape of the nanoparticles depend on the microorganism utilized and experimental condition employed during synthesis process. Nanoparticles synthesized from microbes are safe, environmental benign and have several applications in agriculture, textile, medicine, drug delivery, biochemical sensors and allied areas. Future challenges may include large-scale production, enhancement of stability, reduced time to obtain desirable shape and size and their possible applications in several fields. In this review paper, we provide a brief overview on the emerging role of fungi in the synthesis of metal nanoparticles, possible mechanisms and their potential bio-prospective applications.

“…Biological systems present in water extract of plants is good candidate to be used for the bio-reduction of Ag + ions to Ag-NPs as a green chemical, via a cost-effective and environmentally friendly route [11]. In our previous work, Ag-NPs were successfully prepared with an average size of 15 ± 7.4 nm by the water extract of this plant at ambient temperature without any support [12]. In this project, rapid and eco-friendly bio-reduction method for the synthesizing of Ag-NPs is reported.…”

In this project, facile, rapid biosynthesis and characterization of silver-montmorillonite (MMT) nanocomposite is carried out at ambient temperature. Silver nanoparticles (Ag-NPs) were prepared by water extract of the plant [Satureja hortensis (L)] as the reducing agent and MMT as interlamellar space for controlling the size of Ag-NPs. MMT was sonicated in the aqueous AgNO 3 solution and Ag + ions were reduced to Ag° using water extract of Satureja hortensis (L). The nanocomposite was evaluated using ultraviolet-visible spectroscopy (UV-Vis), X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). TEM study showed the formations of nanocomposite using water extract of Satureja hortensis L in the range of 4.88-26.70 nm and an average particles size of 15.79 nm. In addition, XRD studies indicated that the particles have a face centred cubic (FCC) structure. The nanocomposite showed antibacterial effects against bacteria.

“…Therefore, biological and green approaches for the synthesis of nanoparticles are better than chemical and physical methods due to being clean, non-toxic, cost-effective, environmental friendly (21,22), low energy and time consumption, and non-toxic solvents and non-dangerous materials (23 30-60 cm tall and with short creeping roots. It has narrow leaves arranged alternately on fleshy, bright green stiff stems.…”

In this study, we investigated the synthesis of silver nanoparticles using Peganum harmala water extract at ambient temperature. The Ag nanoparticles (AgNPs) were characterized by ultravioletvisible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and transmission electron microscopy (TEM). The average particle size of the silver nanoparticles was about 23 nm. Inhibitory activity of the synthesized AgNPs was tested against human pathogens like Escherichia coli and Staphylococcus aureus. The results indicated that the AgNPs showed moderate inhibitory actions, demonstrating its antibacterial value against pathogenic diseases. ARTICLE HISTORY
