AgNO3 solution

Porous silicon photonic crystal (PSi PhC) decorated with silver nanoparticles (AgNPs) is shown to provide a new substrate for the improvement of SERS. AgNPs are obtained through immersion of PSi PhC samples in AgNO3 solutions and successive thermal annealing.

The silver nanoparticles are synthesized by the green method using Salix semi-solid extract. Fresh leaves are prepared in a semi-solid extract form that retains active substances and can be preserved for a long time. The parameters of the synthesis process are optimized by examining the effects of pH, Salix semi-solid extract concentrations of extract and AgNO3 concentrations through the UV-Vis absorption spectrum of synthetic particulate solutions.

In this article, we report the biological synthesis of silver nanoparticles from silver nitrate solution using aqueous extract of lemongrass leaf as reducing agent. The influence of some factors such as the volume ratio of lemongrass leaf extract/AgNO3 solution, pH, and temperature to he synthesis of silver nanoparticles was investigated.

Now a day’s nanotechnology has become one of the most promising approaches in pest management. Nanoparticles represent a new generation of environmental remediation technologies that provide cost–effective solution to some of the most challenging insect pests. S.litura (F.) (Lepidoptera: Noctuidae) is a major polyphagous pest of field crops and vegetables, causing severe damage to the plants in all phenological crop stages.

This paper reports an investigation of the microwave-assisted synthesis of silver nanoparticles (Ag NPs) using extract of stinky bean (Parkia speciosa Hassk) pods (BP). The formation of Ag NPs was identified by instrumental analysis consists of UV–vis spectrophotometry, Fourier-transform infrared (FTIR) spectrophotometry, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and particle size analysis. Furthermore, Ag NPs were used as antibacterial agents against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa.
