Nanoapplications have great promise but we should also be aware that due to their size nanoparticles have the risk of being teratogene. Nanotoxicology is a rapid growing field putting nanotech advances in perspective: every advantage has its disadvantage. Great article. Since you are obviously a man of science, have a look at this spectacular breakthrough I posted about today: https://steemit.com/science/@technovedanta/spectacular-science-breakthrough-cells-making-carbon-silicon-bonds-life-but-not-as-you-know-it
