Capitalizing on nanotechnology to address fungal infections topically

Nanowerk.com - 19 июля, 2017 - 09:47
Cutaneous fungal infections involving the skin, hair, or nails affect an estimated 25% of the world's population, and accounts for millions of outpatient visits. Currently, deep fungal infection require systemic therapy, which can pose a range of side effects or drug interactions depending on the clinical scenario. Investigators now have demonstrated the antifungal activity of nitric oxide generating nanoparticles against dermatophytes well known to cause invasive cutaneous infections.

Carbon nanotube wools for greenhouse gas mitigation and bullet-proof clothing

Nanowerk.com - 18 июля, 2017 - 13:28
Turning atmospheric carbon dioxide (CO2) into valuable products seems like a great idea to help remove this greenhouse gas to mitigate climate change. Using a process of molten carbonate electrolytic transformation of CO2 to carbon nanotubes, researchers have now demonstrated 'carbon nanotube wool'. These are the first carbon nanotubes that can be directly woven into a cloth as they are of macroscopic length (over 1mm) and are cheap to produce. The sole reactant to produce the carbon nanotube wools is carbon dioxide. This transforms CO2 from a pollutant into a useful, valuable resource.
