Looks like women won't be the only ones loving diamonds. Apparently according to Northwestern University scientist Dean Ho and his team, nanodiamonds are very attractive to insulin which is well known for regulating blood sugar. It can also accelerate the healing processes and prevent infections in wound sites. Ho says:

Insulin accelerates wound healing by acting as a growth hormone. It encourages skin cells to proliferate and divide, restores blood flow to the wound, suppresses inflammation and fights infection.

What's also interesting is that the only thing that can cause insulin to release from nanodiamonds is the presence of a base pH level which occur in wounds and infected tissue.

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.

This could be a whole new range of therapy for wound treatment and care. And, very bling too.
