Carbon-Nanotube-Coated Ultrasound Acts as Invisible Knife for Noninvasive Surgery

A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. The University of Michigan engineering researchers who developed the new therapeutic ultrasound approach say it could lead to an invisible knife for noninvasive surgery.

Researchers Demonstrate Synchronization at Nanoscale Using Light

Synchronization phenomena are everywhere in the physical world -- from circadian rhythms to side-by-side pendulum clocks coupled mechanically through vibrations in the wall. Researchers have now demonstrated synchronization at the nanoscale, using only light, not mechanics.

New Microscopy Tool to Explore Solar-to-Electric Energy Conversion

If nanoscience were television, we'd be in the 1950s. Although scientists can make and manipulate nanoscale objects with increasingly awesome control, they are limited to black-and-white imagery for examining those objects. Information about nanoscale chemistry and interactions with light—the atomic-microscopy equivalent to color—is tantalizingly out of reach to all but the most persistent researchers.

Innovative Optical Tweezers Trap Nano-Sized Particles

To grasp and move microscopic objects, such as bacteria and the components of living cells, scientists can harness the power of concentrated light to manipulate them without ever physically touching them.

Tunable Plasmonic Nanobubbles Help Advance Medical Applications

Researchers at Rice University have found a way to kill some diseased cells and treat others in the same sample at the same time. The process activated by a pulse of laser light leaves neighboring healthy cells untouched.

Researchers Develop New Blood Flow Visualization Technique Using Carbon Nanotubes and Lasers

Stanford scientists have developed a fluorescence imaging technique that allows them to view the pulsing blood vessels of living animals with unprecedented clarity. Compared with conventional imaging techniques, the increase in sharpness is akin to wiping fog off your glasses.
