Extracellular biogenic synthesis of silver nanoparticles with various shapes using the rice bacterial blight bacterium Xanthomonas oryzae pv. oryzae BXO8 is reported. The synthesized silver nanoparticles were characterized by UV-Vis spectroscopy, powder X-ray diffractometry (XRD), scanning electron microscopy, energy dispersive X-ray spectrometry, and highresolution transmission electron micros...

   The use of plant extract in the biosynthesis of nanoparticles (NPs) can be an eco-friendly approach and have been suggested as a possible alternative to classic methods namely physical and chemical procedures. This study was designed to examine the structural chemistry of silver nanoparticles (AgNPs) using both conventional heating and microwave irradiation methods.To o...

Here, we explored the medicinal uses of the novel biogenic silver nanoparticles of Pterospermum acerifolium (PaAgNPs) as a cost effective, eco-friendly, reducing and stabilizing compounds. The formation of PaAgNPs was confirmed by changing its color from colorless to yellowish brown, with maximum absorbance at 417 nm. FTIR spectrum of PaAgNPs suggested the presence of polycyclic compound simila...

The biogenic synthesis of metal nanomaterial offers an environmentally benign alternative to the traditional chemical synthesis routes. In the present study, the green synthesis of silver nanoparticles (AgNPs) from aqueous solution of silver nitrate (AgNO3) by using Nigella arvensis L. seed powder extract (NSPE) has been reported. AgNPs were characterized by UV–vis absorption spectroscopy with ...

This chapter describes the biological synthesis of anisotropic metal nanoparticles using the bacterium Actinobacter spp. The biogenic gold nanoparticles thus synthesized show triangular and hexagonal morphology with edge lengths between 0.05 μm to 2 μm. The surface topography of triangular gold particles indicated that they are ~ 9 nm thick. These flat particles show a strong absorption in the ...

Skin infections caused by fungi, such as Trichophyton and Candida species, have become more common in recent years. This upward trend is concerning,considering the limited number of antifungal drugs available because prophylaxis with antifungals may lead to the emergence of resistant strains and various virulence factors produced by the organism inactivate the drugs. Exploitation of principles ...
