Engineers create chip-based tractor beam for biological particles

Integrated OPA tweezers concept. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-52273-x Researchers at MIT have developed a small chip-based “tractor beam” similar to the one seen on the Millennium Falcon in the “Star Wars” movies. This could one day help biologists and clinicians study DNA, classify cells, and investigate disease mechanisms. . The study is published in the journal Nature Communications.…
