Levan-Capped Silver Nanoparticles for Bactericidal Formulations: Release and Activity Modelling

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...

Synergistic Bactericidal Activity of Silver Nanoparticles and Ciprofloxacin against Phytopathogens

The present study is to concentrate on the synergistic bactericidal effect of silver nanoparticles and ciproflaxacin against Pseudomonas solanocearum, Pseudomonas syringae, Xanthomonas malvacearum and Xanthomonas campestris. Silver nanoparticles were prepared in 0.1mM, 0.2 mM and 0.3 mM by Spirulina platensis. It exhibited anti microbial activity against all phytopathogens with varying degrees....

Laser-fabricated castor oil-capped silver nanoparticles

Silver nanoparticles were fabricated by ablation of a pure silver plate immersed in castor oil. A Nd:YAG-pulsed Q-switch laser with 1064-nm wavelength and 10-Hz frequency was used to ablate the plate for 10 minutes. The sample was characterized by ultraviolet-visible, atomic absorption, Fourier transform-infrared spectroscopies, and transmission electron microscopy. The results of the fabricate...

The bactericidal effect of silver nanoparticles.

Nanotechnology is expected to open new avenues to fight and prevent disease using atomic scale tailoring of materials. Among the most promising nanomaterials with antibacterial properties are metallic nanoparticles, which exhibit increased chemical activity due to their large surface to volume ratios and crystallographic surface structure. The study of bactericidal nanomaterials is particularly...
