Optical trapping studies of irregularly shaped microplastic particles
Using optical tweezers and Raman spectroscopy, we created a database of optical trapping responses for common microplastics found in nature. We studied how shape, composition, and size affect the stability of irregularly shaped particles. The analysis included lab-made microplastics from household plastics (PP, PET, HDPE), nature-collected samples from Los Angeles County beaches, and simulation results for the optical trapping stability of spheroidal particles.
