The present study demonstrates exopolysaccharide production by an osmotolerant marine isolate and also describes further application of the purified polysaccharide for production of colloidal suspension of silver nanoparticles with narrow size distribution. Phylogenetic analysis based on 16S r RNA gene sequencing revealed close affinity of the isolate to Alteromonas macleodii. Unlike earlier re...

In the present study, microwave-assisted, optimized, instant, Terminalia bellirica fruit extract-mediated green synthesis of colloidal silver nanoparticles (AgNPs) has been reported. The synthesized AgNPs were characterized by UV-Vis spectroscopy, FTIR, Zetasizer, FESEM, EDX and XRD. The characteristic surface plasmon peak of reaction mixture at 406 nm confirmed the synthesis of AgNPs. The FTIR...

The field of nanobiotechnology mainly encompasses with physics, biology, chemistry and material sciences and it develops novel therapeutic nano-scale materials for biomedical, drug delivery, cancer therapy and pharmaceutical applications. Silver nanoparticles (AgNPs) have unique physiochemical, biological and environmental properties which make them useful in a wide range of applications, s...

Preparation of silver-alginate nanocomposite films as an antibacterial material has been carried out through the casting method colloidal silver-alginate. Colloidal was made by chemical reduction AgNO 3 precursor salts using microwave irradiation with alginate a stabilizer and reducing agent NaOH accelerator. The appearance brownish yellow color, due to addition variation , localized surface pl...

BACKGROUND There is an increasing commercial demand for nanoparticles due to their wide applicability in various markets, including medicine, catalysis, electronics, chemistry, and energy. In this report, a simple and ecofriendly chemical reaction for the synthesis of gold and silver nanoparticles from Trianthema decandra (Aizoaceae) has been developed. METHODS AND RESULTS On treatment of aqu...

in the present study, we have reported the biological synthesis of silver nanoparticles (agnps) using aqueous leaf extract prepared by hot percolation treatment of wheat varities (pbw343, triticum durum and aegilops tauschii )for the reduction of silver ions to silver nanoparticles. bioreduction of ag+ to ag0 was observed when aqueous extract augmented with silver nitrate (agno3) was incubated ...
