Go For Gold - I Mean Nanoparticles And Drugs

This just caught my eye, Team Designs Gold Nanoparticles to Deliver Multiple Drugs. This is really unusual. Build some gold nanoparticles with drugs stuck on them, and with the right infrared exposure, the gold releases the drugs. The MIT research team reports that when exposed to infrared light, the gold nanoparticles melt, releasing drug payloads attached to their surfaces. They built two different shapes of nanoparticles, called "nanobones" and "nanocapsules." Nanobones melt at light wavelengths of 1,100 nanometers, nanocapsules at 800 nanometers. The team thinks this technique could one day provide more control of diseases commonly treated with more than one drug, by attaching mulple drugs to the surface of the nanoparticles.

Very cool, don't you think?!
