Soil bacteria Cupriavidus sp. Mediates the extracellular synthesis of antibacterial silver nanoparticles
Publication date: Available online 15 October 2019Source: Journal of Molecular StructureAuthor(s): F. Ameen, S. AlYahia, M. Govarthanan, N. ALjahdali, N. Al-Enazi, K. Alsamhari, W.A. Alshehri, S.S. Alwakeel, S.A. AlharbiAbstractSilver nanoparticles (AgNPs) were synthesized extracellularly using a bacterium Cuprividus sp., which was isolated from urban soil and assumed be heavy metal resistant. The successful synthesis of nano size (10–50 nm) spherical crystalline particles was shown by microscopic, diffractometric and spectroscopic analyses. Further, the FTIR spectrum of the AgNPs indicated the presence of amides, which ...

Surface functionalized nanoparticles: A boon to biomedical science
Chem Biol Interact. 2023 May 12:110537. doi: 10.1016/j.cbi.2023.110537. Online ahead of print.ABSTRACTThe rapid development of nanomedicine has increased the likelihood that manufactured nanoparticles will one day come into contact with people and the environment. A variety of academic fields, including engineering and the health sciences, have taken a keen interest in the development of nanotechnology. Any significant development in nanomaterial-based applications would depend on the production of functionalized nanoparticles, which are believed to have the potential to be used in fields like pharmaceutical and biomedical...

The Effects of Serum Albumin Pre-Adsorption of Nanoparticles on Protein Corona and Membrane Interaction: A Molecular Simulation Study
In this study, we performed molecular dynamics simulations to study the adsorption mechanism of nanoparticles with various surface modifications and different proteins (e.g., human serum albumin, complement protein C3b), and their interactions with cell membrane. The results show that protein human serum albumin prefers to interact with hydrophobic and positively charged nanoparticles, while the protein C3b prefers the hydrophobic and charged nanoparticles. The pre-adsorption of human serum albumin on the nanoparticle surface obviously decreases the interaction of nanoparticle with C3b. Furthermore, the high amount of prot...

Exposure to lutein-loaded nanoparticles attenuates Parkinson's model-induced damage in Drosophila melanogaster: restoration of dopaminergic and cholinergic system and oxidative stress indicators
Chem Biol Interact. 2021 Mar 11:109431. doi: 10.1016/j.cbi.2021.109431. Online ahead of print.ABSTRACTParkinson's is a neurodegenerative disease, characterized by the loss of dopaminergic neurons, cholinergic alterations and oxidative damages. Lutein is widely known by its antioxidants properties. In the present study, we investigated whether lutein-loaded nanoparticles protects against locomotor damage and neurotoxicity induced by Parkinson's disease model in Drosophila melanogaster, as well as possible mechanisms of action. First, the nanoparticles were characterized by physicochemical methods, demonstrating that water a...

ZnO, TiO2 and Ag nanoparticles impact against some species of pathogenic bacteria and yeast
Cell Mol Biol (Noisy-le-grand). 2021 Nov 25;67(3):24-34. doi: 10.14715/cmb/2021.67.3.4.ABSTRACTThe economic approaches for manufacturing the nanoparticles with physical and chemical effects and limited resistance to antibiotics have been progressed recently due to the rise of microbial resistance to antibiotics. This research aimed to study the antimicrobial efficacy of silver nanoparticles Ag, ZnO, and Tio2 nanoparticles against Salmonella typhimurium and Brucella abortus and Candida albicans. Two isolates of Salmonella and two isolates of Brucella abortus were isolated from food spastically meat and blood specimens, resp...
