Optical and Raman tweezers for the manipulation and characterization of cosmic dust and sea microplastics
AI summary Read the abstract
Researchers used optical and Raman laser tweezers to manipulate and identify individual micro- and nanoplastic particles and cosmic dust grains. The technique can characterize particle composition and fragmentation behavior, offering a powerful new approach for studying how microplastics break down in the ocean.
We use optical and Raman Tweezers to manipulate micro and nano-plastics and individual cosmic dust particles. We identify their compositions and shapes studying their response to optical forces, enabling a better understanding of the plastics fragmentation processes in sea environment and the effects of light on single grains of cosmic dust.
