According to Dr. Karp, chemists, material scientists and immunologists are involved in the research. They've created a needle with a clutch, inspired by oil drilling. It's designed to never overshoot its mark. The researchers have also developed a gel that could be injected into an arthritic joint to attack pain. It would only activate in the presence of inflammation.
Dr. Karp is one of millions of people who suffer from nickel allergy, so he's helped the team come up with a nanoparticle cream. He says when you rub it into your skin, it will capture the nickel and prevent it from penetrating the skin. He believes that the the nickel allergy cream could be available to the public within a few years. Some of the other devices and technologies could take a lot longer to hit the market
