A team at Northwestern University, led by Dean Ho, has discovered that nanodiamonds are a wound's best friend. Insulin is very attracted to nanodiamonds and in addition to regulating blood sugar, insulin can accelerate the healing process and stave off infection in wound sites. Since the tiny diamond can be easily placed in a wound without causing further damage, this is an excellent way to get an increased amount of insulin there as well. From the article, "A substantial amount of insulin can be loaded onto the nanodiamonds, which have a high surface area. The nanodiamond-insulin clusters, by releasing insulin in alkaline wound areas, could accelerate the healing process and decrease the incidence of infection. Ho says this ability to release therapeutics from the nanodiamonds on demand represents an exciting strategy towards enhancing the specificity of wound treatment."
