Toxicity Reduction of Polymer-Stabilized Silver Nanoparticles by Sunlight

摘要: The environmental and health impacts of nanomaterials are becoming important topics research in recent years. unique advantages offered by these wide range applications cannot be realized until concerns resolved. Among all the nanomaterials, Ag nanoparticles, due to their existing extensive uses commercial products, demand immediate attention. Since nanoparticle suspensions will exposed conditions different from a lab setting, many factors, including light, temperature, salinity, etc., suspected affect stability also toxicity. In this study, we examined effect sunlight on toxicity 6 25 nm nanoparticles coated with gum arabic (GA) polyvinylpyrrolidone (PVP). Under irradiation, irreversibly aggregated degrees depending surface coating. UV content is identified driving forc...
