Raman spectroscopy is based on the principle of inelastic light scattering, enabling precise analysis and identification of materials by detecting spectral characteristics of low-frequency modes such as vibrations and rotations in molecules, solids, and two-dimensional materials. This technology offers advantages including label-free detection, rich information content, and non-destructive analysis, demonstrating broad application prospects in chemistry, biology, medicine, environmental science, and other fields. However, as a higher-order light-matter interaction process, Raman scattering has an inherently tiny scattering cross-section, with signal intensity far lower than fluorescence and Rayleigh scattering.

Lehigh University materials science and engineering (MSE) professor Christopher J. Kiely has been named the 2025 recipient of the Microanalysis Society (MAS) Presidential Science Award, which honors a senior scientist for “outstanding technical contributions to the field of microanalysis over a sustained period of time.”

Researchers at the University of Bath have developed a new technology that, for many patients could make injections a thing of the past. The new system could be used in the future for a range of treatments including growth hormone, immunotherapy cancer treatments, and diabetes and weight management treatments such as Wegovy and Ozempic.

A research team led by SUTD proposes a quantum-enhanced framework for processing complex topological signals that could one day outperform classical methods in recommendation systems, network science, and more.
