One-Step Synthesis Of Kanamycin Functionalized Gold Nanoparticles With Potent Antibacterial Activity Against Resistant Bacterial Strains, Hitesh Kumar Waghwani May 2015

One-Step Synthesis Of Kanamycin Functionalized Gold Nanoparticles With Potent Antibacterial Activity Against Resistant Bacterial Strains, Hitesh Kumar Waghwani

Masters Theses & Specialist Projects

On the verge of entering the post-antibiotic era, numerous efforts are in place to regain the losing potential of antibiotics which are proving ineffective against common bacterial infections. Engineered nanomaterials, especially gold nanoparticles (GNPs) capped with antibacterial agents are proving to be an effective and novel strategy against multi-drug resistant (MDR) bacteria. In this study, we report a one-step synthesis of kanamycin-capped GNPs (20 ± 5 nm) utilizing the combined reducing and capping ability of the aminoglycoside antibiotic, kanamycin. Antibacterial assays showed dosedependent broad spectrum activity of Kan-GNPs against Gram-positive (Staphylococcus epidermidis and Enterococcus durans), Gram-negative (Escherichia coli and Enterobacter aerogenes ...

Antimicrobial Nanoparticles: A Green And Novel Approach For Enhancing Bactericidal Efficacy Of Commercial Antibiotics, Monic Shah

Masters Theses & Specialist Projects

On the verge of entering the post-antibiotic era, numerous efforts are in place to regain the waning charm of antibiotics which are proving ineffective against most “Superbugs”. Engineered nanomaterials, especially gold nanoparticles (GNPs) capped with antibacterial agents, are proving to be an effective and novel strategy against multidrug resistant (MDR) bacteria. In this study, we report a one-step synthesis of antibioticcapped GNPs (25 ± 5 nm) utilizing the combined reducing and capping ability of a cephalosporin antibiotic, ceftazidime. No signs of aggregation or leaching of ceftazidime from GNP surface was observed upon its storage. Antibacterial testing showed dosedependent broad spectrum activity ...
