Northwestern University is using nanodiamonds to deliver insulin to fight infection and heal wounds. Perhaps they’re not just a girl’s best friend anymore? Just kidding, nanodiamonds would never be visible or good for resale. Read about it here.

It’s actually very interesting to have new ways to beat infection. Nanodiamonds are something I haven’t heard of. I might have to do some research to figure out what else they could be used for!
