Biosynthesis of silver nanoparticles using pennyroyal water extract as a green route

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.

“…AgNPs can be synthesized using physical or chemical methods such as ultrasonic fields, ultraviolet and microwave radiation, photochemical reduction, and also photochemical and sonoelectrochemical methods. However, the use of toxic chemicals as reducing agents in many of these processes, which is potentially dangerous to the environment and biological systems, is of great concern (5,6). Compared with other methods, biological methods using microorganisms (7,8), enzymes (9), and plants or plant extracts like Nothapodytes nimmoniana (Graham) Mabb.…”

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

The biosynthesis of nanoparticles is an important field in nanotechnology which can be developed as: eco friendly, rapid and green route compared to traditional methods. In this work, green biosynthesis of silver nanoparticles (Ag-NPs) using glucose solution as a reducing and capping agent is carried out at ambient temperature. The synthesized Ag-NPs were characterized by UV-Vis, FTIR, XRD and TEM analysis. The UV-Vis spectral studies confirmed the surface plasmon resonance of biosynthesized silver nanoparticles. TEM results showed that mean diameter of silver nanoparticles were about 11 nm.
