Although liposuction is one of the most common and well-established cosmetic surgery procedures in the U.S., it still has its drawbacks. But a new biomedical start-up says it may have found a novel way to improve the procedure using gold nanoparticles to literally melt fat, reports Chemical & Engineering News (C&EN), the weekly news magazine of the American Chemical Society.
