In study, spherical Silver nanoparticles (SNPs) were synthesized by chemical reduction method from a metal precursor silver nitrate in presence of an anionic surfactant and strong reducing agent. In this experimental work, SNPs are synthesized in presence of different concentration of stabilizing agent and effect of stabilizing agent on size distribution of SNPs have been observed. Further anti...

Background Single nucleotide polymorphism (SNPs) are considered as one of the underlying causes of male infertility. Proper sperm chromatin packaging which involves replacement of histones with protamines has profound effect on male fertility. Over 20 SNPs have been reported for the protamine 1 and 2. MaterialsAndMethods The aim of this study was to evaluate the frequency of two previously repo...

Characterization and the antibacterial potential of gold (AuNPs) and silver nanoparticle (SNPs) biosynthesized greenly using exopolysaccharides (EPS) and Culture Free Supernatant (CFS) of Wesiella confusa against some multidrug resistance (MDR) E. coli was investigated. The biosynthesized nanoparticles were characterized by UV-visible spectra, Fourier Transfor...

background and objectives: bacillus anthracis is one of the most homogenous bacteria ever described. bacillus anthracis 17jb is a laboratory strain. it is broadly used as a challenge strain in guinea pigs for potency test of anthrax vaccine. material and methods: this work describes genetic characterization of b. anthracis 17 jb strain using the snps and mlva genotyping. results and conclusion:...

The present study evaluates the biosynthesis of silver nanoparticles (SNPs) mediated by xerophytic plants, Cynanchum viminale and Cynanchum sarcomedium. The reaction between plant extracts and silver nitrate solution resulted in a yellowish brown/dark brown colored solution which suggests the formation of SNPs. Physical characteristics of synthesized SNPs were determined using...
