Curcumin halloysite nanoformulation with selective antimicrobial effects

NanoWerk.com - Mon, 07/15/2019 - 13:26
Turmeric has a long history of usage in traditional medicine in India and China. Ancient Indians have known the medicinal properties of turmeric - i.e. curcumin - for several millennia. Researchers have now investigated the antibacterial effects of curcumin loaded into halloysite nanotubes and found that this nanoformulation drastically increased the life expectancy of nematodes infected by pathogenic bacteria. The most interesting finding here is the selective antimicrobial action of curcumin, which suppressed one bacterial species, while demonstrating no adverse effect on another.
