For at least a decade, researchers have tried to develop practical ways to use gold nanoparticles to kill cancer cells. But perhaps you'll see the nanotechnology in a cosmetic surgeon's office before you see it at the oncologist's. A new startup, NanoLipo, is working on a gold nanoparticle-based liposuction alternative, Chemical & Engineering News reports.
The idea is that doctors would inject their patients' unwanted fat with the particles, then use a laser to heat up the particles, which would melt the fat around them. Doctors would use needles to suction out the liquefied fat. Researchers have investigated heating gold nanoparticles to kill cancer cells, too.
