Nanoparticle Coated Lens Converts Light into Sound for Precise Non-invasive Surgery

Abstract:
Remember how Leonard McCoy performed surgery in Star Trek? He would wave a device over the patient. The outer layers of the skin didn't need not be cut, even when operating on internal organs, and the precision of 23rd century instrument reached down to the level of individual cells.

Well, we already have a bit of that in the 21st. Research at the University of Michigan, led by Jay Gou, has developed a device that employs a carbon-nanotube-coated lens capable of converting light into tightly focused sound waves. The new ultrasound therapeutic tool that reaches new levels of precision—its high-amplitude sound waves are able to target an object with dimensions of 75 by 400 micrometers.
