Hydroxyl capped silver-gold alloy nanoparticles: characterization and their combination effect with different antibiotics against Staphylococcus aureus

Objective(s):   Metal nanoparticles (NPs) offer a wide variety of potential applications in pharmaceutical sciences due to the unique advances in nanotechnology research. In this work, bimetal Ag-Au alloy NPs were prepared and their combinations with other antibiotics were tested against Staphylococcus aureus.   Materials and Methods: Firstly, Ag-Au alloy NPs with Au/Ag molar ratio of 1:1 was f...

effect of silver nanoparticles on the antibacterial activity of different antibiotics against staphylococcus aureus and pseudomonas aeruginosa

Antimicrobial Effect of Silver Nanoparticles on Staphylococcus Aureus

Background: Development of new antimicrobial drugs targeting virulence factors of pathogenic bacteria is an effective strategy to address increasing emergence of resistant bacterial strains. Considering the clinical importance of Staphylococcus aureus and global emergence of antibiotic-resistant strains of this pathogen, the present study was carried out to investigate the inhibitory effects of...

Synergistic Effects of Gold Nanoparticles Mixed with Gentamicin, Erythromycin, Clindamycin, Bacitracin, and Polymyxin B against Staphylococcus aureus, Staphylococcus saprophyticus, Staphylococcus epidermidis, Enterococcus faecium and Enterococcus fae

Background and Objective: The majority of bacterial infections are now treatable using different classes of antibiotics. However, the world has faced a challenge called antimicrobial resistance that will diminish most antibiotics' beneficial impacts. A valuable strategy to prevent this adverse phenomenon is to increase the antibacterial effects of antibiotics using various materials as antibiot...

synthesis and the combination effects of dihydropyridine analogs with selected antibiotics against resistant staphylococcus aureus

bacterial resistance is a major drawback in chemotherapy of infectious diseases. in this investigation a new series of 3,5-diarylamide dihydropyridines containing 2-benzylsulfonylimidazol at 4 position have been synthesized and studied for their enhancing effect on the antibacterial activities of different penicillins against a resistant clinical isolate of s. aureus using disc diffusion method...

Dithiocarbamate-capped silver nanoparticles.

Nanometer-sized silver particles were synthesized by using didecylamine dithiocarbamates as the protecting ligands. With control of the initial ligand-metal feed ratios, the core diameter of the resulting particles was found to vary from about 5 to 2.5 nm, as determined by transmission electron microscopic measurements. The core size dispersity was also found to decrease with increasing feed ra...
