Healing Wounds With Diamonds 109

Posted by samzenpus from the 14-carats-and-23-stiches dept.
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."

    The article leaves a lot to be desired. Can anyone explain why it is that insulin's attracted to diamonds, or more specifically, nanodiamonds?

    Apart from the "insulin = women" comments we're sure to get, I'm seriously wondering why.

      The insulin molecule has two patches on its surface that are predominantly hydrophobic (water-hating) that likely help it to stick to the pure-carbon surface of (nano)diamond. The "nano" bit just insures there is a large amount of surface area for insulin to stick to per unit mass of diamond. The investigators only showed that their nanodiamonds can suck up a lot of insulin; they are far from proving their insulin-loaded nanodiamonds are useful for wound-healing. The investigators only speculate that insulin would act as a growth hormone (generally thought to be its minor function; the major function being the transsystem signal for organism-wide glucose homeostasis). They point out the pH in a typical wound could approach 10.5, which would facilitate insulin release from nanodiamonds. (Such increases in alkalinity in beta cells, the pacreatic cells that produce insulin, are thought to trigger its release.) Unfortunately, it might also compromise insulin's ability to dock with its receptor, a necessary requirement for its function (either as a growth hormone or in glucose regulation). Directly injecting insulin into wounds speeds healing (sometimes by 50%) (Zhang et al, J. Surg. Res. 142:90 (2007) link [doi.org]), so it seems like the investigators have a plausible path to follow.
    • Well you see insulin is allot like women, they can make you weak and pass out into a deep peaceful sleep slumber, but not enough can cause hyperglycemic shock leading to coma and eventually death. Uncanny. On a side note, what's the cost of treatment? I'm assuming this won't be available on the NHS.

          HMO is "health maintenance organization". Remember, we do not have national medicine in the USA, we instead have medical insurance companies. There are two primary types of plans one can get, an HMO or a PPO (Preferred Provider Organization), the difference is in which doctors you can see, how much you pay, and the process through which you must visit specialists.

        There is no reason to use wild diamonds. Perfectly pure diamonds can be manufactured relatively cheaply. These are way better quality and way cheaper than you can find in the wild. Something the cartels don't want people to know about so they can set those artificial prices.

      Eh, I don't think so. Industrial-grade diamonds and artificially-created diamonds are not insanely expensive. It's only once you start going with "natural" jewelry-grade diamonds with good clarity/cut/carat that prices start going insane.

      Artificially created diamonds are not fakes... they're still diamonds in every sense of the work (chemically and such).

      So if you produced these things artificially, and bumped up serious production to meet healthcare needs, the price might actually come down to sane level
