<ul><li>Researchers from MIT have developed a miniature, chip-based optical trap that can manipulate particles up to 5 mm away from the chip surface.</li><li>The device, made from a silicon-photonics chip, can act as a 'tractor beam' for studying DNA, classifying cells, and investigating disease mechanisms.</li><li>The chip-based optical trap allows particles to be trapped and manipulated at larger distances from the chip's surface, making it suitable for biological research.</li><li>The device is reusable, biocompatible, and maintains a sterile environment for cells during manipulation.</li></ul>
