Surgeons run with nano-scissors

'Nano-Scissors' Laser Shows Precise Surgical Capability (Science Daily)

    nanoscissorsAn ultra-short pulse laser that can perform extremely precise surgery on tiny roundworms may be the key to understanding nerve regeneration and is an important step toward treatment of human neurological disease, according to research published in the Dec. 16 issue of Nature.

    Dr. Adela Ben-Yakar, an assistant professor of mechanical engineering at The University of Texas at Austin, led the development of the technique. It acts like a pair of tiny “nano-scissors,” able to cut, for example, nano-sized units like nerve axons, the parts of nerve cells that carry nerve impulses away from the cells to muscles or to other cells.

    “This tool opens up a new frontier for biologists studying nerve regeneration,” says Ben-Yakar. “We can also apply it to many other studies that require nanosurgery, so it’s a very versatile tool.” More here
