Optical tweezers have been used by biophysicists since their invention at Bell Labs in the 1980s, and are typically used to study cellular components. But they have a few drawbacks, not least of which are overheating and inefficiency.
So engineers at Harvard have been working on a next-gen model they call plasmonic nanotweezers to solve those and other issues with traditional optical tweezers so that tiny particles such as viruses can be isolated, observed, and manipulated. via crave/cnet
