Raman Spectroscopy

Researchers from India developed a new micro-Raman spectroscopy system to detect and analyze microplastics.

Microplastics (MPs) and nanoplastics (NPs) are emerging contaminants that require robust analytical techniques for identification and quantification across diverse environmental and biological matrices. This review highlights various spectroscopy methods, including Raman, FT-IR, NIR, ICP-MS, Fluorescence, X-ray, and NMR, and details their methodologies, sample handling, and applications for characterizing MPs and NPs.

A novel method using fluorescence labeling and differential Raman spectroscopy claims to offer a more efficient, accurate approach to detect microplastics in seawater. Developed by researchers at the Ocean University of China, this method improves both the speed and precision of microplastic identification, addressing a key environmental issue affecting marine ecosystems.
