U.S. scientists devised a new way to provide drugs for pain relief
the technique, which requires no needles, could improve the lives of millions of people suffering from chronic pain or disorders that require powerful painkillers to be injected for long periods.

The strategy, designed by researchers at Children’s Hospital Boston, magnetism combines with nanotechnology.

This requires a small device that is implanted in the patient of just over 1 inch in diameter, says research published in the journal Nano Letters.
Smart Nanoparticles

“The device is specially created a membrane on which they are embedded nanoparticles (structures of the one hundred thousandth of the thickness of a human hair) in a gel composed of magnetite, an iron ore with natural magnetic properties,” he told the BBC: Dr. Daniel Kohane, who led the research.

“When outside the body turns on a magnetic field near the device, the nanoparticles are heated causing it to shrink and this in turn causes the opening of small spaces, neck, and allowing movement of nanogel from one side to another” says the scientist. Read the rest of this entry »
