Exposed Identity: Microplastics Under The Raman Microscope
AI summary Read the abstract
This presentation described using Raman microscopy to identify and characterize microplastics, demonstrating how this spectroscopic technique can reveal the identity of tiny plastic fragments found in marine organisms, food products, and drinking water.
The issue of microplastic pollution is raising serious concern among scientists and the society at large 1,2. Microplastics, tiny plastic fragments ranging from 1 micron to 5 millimetres in size, have found their way into a variety of terrestrial and aquatic environments 3,4, marine organisms 5and even consumer products, including food 6–8and drink 9.
