Engineers from University of Michigan have created a new ultrasound technology that promises to be a boon for micro-surgery.
Using a carbon nanotube coated lens, researchers found that light energy can be converted to high pressure sound waves, to help focus on precise points.
Researchers have called it the 'Invisible Knife' and feel that it can be used in medical research fields like noninvasive surgery. Engineers used tightly-focused sound waves for micro-surgery with which they were able to drill a 150-micrometer hole in a minute artificial kidney stone. They were able to focus high-amplitude sound waves to tiny dot.
According to Jay Guo, a professor of electrical engineering and computer science, mechanical engineering, and macromolecular science and engineering, this research will be the gateway to many more inventions in this area and perhaps even a way to "probe cells or tissues in much smaller scale."
