A new optical technology that lines up living cells and controls their movements has opened the door to better artificial tissues and wounds that heal faster with less scarring.
Star Trek scanners that fix injuries with beams of light may not be science fiction after all. A new optical technology that lines up living cells and controls their movements has opened the door to better artificial tissues and wounds that heal faster with less scarring.
For years, scientists have used the energy in laser light to drill microscopic holes or as tweezers or traps to direct and maneuver small pieces of matter. Guiding entire cells, though, has proven difficult because the lasers used for manipulation tend to damage the structural units of living organisms.
