Confocal Raman Imaging of Diamond Film

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

An interview with Paul Pudney, a winner of the William F. Meggers Award.

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.

Volker Deckert, the winner of the 2013 Charles Mann Award, is advancing the use of tip enhanced Raman spectroscopy (TERS) to push the lateral resolution of vibrational spectroscopy well below the Abbe limit, to achieve single-molecule sensitivity. Because the tip can be moved with sub-nanometer precision, structural information with unmatched spatial resolution can be achieved without the need of specific labels.

This study provides an overview of correlative Raman imaging, PL and topographic analyses of compound semiconductors used to characterize composition and defects.
