Characterizing Microplastics with Raman Spectroscopy
As the need to manage plastic waste increases, researchers are using Raman spectroscopy to characterize the toxicity of polymers and identify their sources. Several technologies exist for characterizing microplastics, including pyrolysis gas chromatography/mass spectrometry, Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy.

Visible Resonance Raman Spectroscopy Could Advance Tumor Identification
A team of researchers from the U.S. and China, led by Robert Alfano from City University of New York, has used visible resonance Raman (VRR) spectroscopy to identify and grade gliomas, a common tumor of the central nervous system. The researchers used in situ spectral biomarkers to identify the tissue from the interface between brain cancer and normal tissue and to evaluate glioma grades.

Photoluminescence Spectroscopy Optimizes Perovskite Quantum Dots
During research and development of perovskite QDs, the emission properties of synthesized QDs must be characterized and this information must then be used to refine subsequent designs and syntheses. The most powerful way to characterize the emission properties of these materials is by using photoluminescence spectroscopy.
