This study was performed to understand how the choice of cytotoxicity assay format affects the observed biocompatibility of nanosilver (nAg). nAg coatings are physical coatings containing silver (Ag) that have feature sizes of 100 nm or less, often in the form of nanoparticles or grains. They are used on medical devices to prevent infection, but in spite of this intended benefit, observations of potential...
Plant based biosynthesis of nanoparticles is a green chemistry methodology that has been claimed as a simple, cost effective and environmental friendly process, alternatively to the conventional methods (chemical and physical). Nanosilver (NS) synthesis by a biological route using Orthosiphon stamineus aqueous leaf extracts has been studied. The NSs were characterized using UV-vis spectroscopy, transmission...
In an attempt to find alternatives to fungicides, the efficacy of crude extracts of seven plant species (Cassia senna, Caesalpinia gilliesii, Thespesia populnea var. acutiloba, Chrysanthemum frutescens, Euonymus japonicus, Bauhinia purpurea and Cassia fistula), three microbial culture filtrates (Epicoccum nigrum, Bacillus subtilis and Bacillus pumilus) and silver nanoparticles were evaluated against...
