Reducing Environmental Toxicity of Silver Nanoparticles through Shape Control.

摘要: The use of antibacterial silver nanomaterials in consumer products ranging from textiles to toys has given rise concerns over their environmental toxicity. These materials, primarily nanoparticles, have been shown be toxic a wide range organisms; thus methods and materials that reduce toxicity while retaining useful properties can potentially solve this problem. Here we demonstrate nanocubes display lower toward the model plant species Lolium multiflorum showing similar other environmentally relevant organisms (Danio rerio Caenorhabditis elegans) bacterial (Esherichia coli, Bacillus cereus, Pseudomonas aeruginosa) compared quasi-spherical nanoparticles nanowires. More specifically, L. experiments, roots nanocube treated plants were 5.3% shorter than control, nanoparticle 39.6% t...
