Microplastic identification using Raman microsocpy
Summary
Researchers developed and implemented a Raman spectroscopy system for rapid detection and identification of microplastic particles on substrates. The system enables efficient chemical characterization of microplastics found across diverse environmental matrices including ocean, lakes, soil, beach sediment, and human blood.
The manufacturing of plastics has expanded enormously over the previous half-century. Degradation of plastic leads to microplastics (MP's) which appear to have become increasingly common in the environment. They have been found almost everywhere, inlcuding ocean, lakes, soil beach, and even human blood [1]. Thus, in terms of identifying MP's, highly efficient analytical techniques need to be developed. We developed and implemented a Raman-system, which enables rapid detection of microplastics on a substrate. The presentation will demonstrate the setup's development and use of it for the detection of microplastics. [1] Leslie, H. A. et al.
