Raman spectroscopy News
Part by Part: The Anatomy of a Raman Microscope
Feb 1, 2024 — Raman microscopy is a fantastic technique for analyzing the chemical composition of samples. It is a nondestructive technique that mitigates the need for material preparation and the use of stains or dyes. Further, combining Raman spectroscopy with microscopy enables high spatial resolution to be obtained that can be applied to particles measuring a few micrometers in size. This versatility has prompted use of the technology in a wide range of applications and end markets, from semiconductors...
Raman Approach Safely Tracks Live-Cell RNA Expression
CAMBRIDGE, Mass., Jan. 22, 2024 — Single-cell RNA sequencing enables scientists to interrogate cells at extraordinary resolution and scale. However, the sequencing process destroys the cell, making it difficult to use the technique to study ongoing changes in gene expression. Raman...
Optical-Plasmonic SERS Platform Clocks Molecular Systems
HONG KONG, Jan. 10, 2024 — An optical plasmonic tweezer-controlled surface-enhanced Raman spectroscopy (SERS) platform developed by Hong Kong University of Science and Technology (HKUST) enables efficient, high-throughput, single-molecule characterization in solution. It has...
Laser Technology Mobilizes Head Trauma Assessment
BIRMINGHAM, England, Dec. 14, 2023 — The decisions made about patient care in the hour following a traumatic brain injury (TBI) are critical to patient outcome. A hand-held diagnostic device to assess the severity of the injury immediately, at the point of care, could make the...

Raman Instrument Advances Study of Greener Fuels for Aerospace
WASHINGTON, D.C., Sept. 20, 2022 — There is much interest in developing aerospace engines that run on renewable, hydrogen (H2-rich) fuels. In addition to providing sustainability, these fuels exhibit a high specific impulse (i.e., the measure of how efficiently the chemical reaction...
Air Lasing Augments Spectroscopic Method for Remote Detection
SHANGHAI, June 24, 2022 — Researchers at the Shanghai Institute of Optics and Fine Mechanics (SIOM) demonstrated how air lasing, a technique deployed in ambient air that is induced by femtosecond laser pulses and that generates cavity-free amplification in the air, could be...
Photonics Brings Laboratory Analysis and Insights to Cultural Conservation
Apr 25, 2022 — The use of lasers for art conservation was pioneered by American research physicist John Asmus, who, in 1972, first leveraged lasers to clean marble sculptures in Venice without harming the underlying works. Over the next 30 years, Asmus further...
Raman Spectroscopy’s Signals and Future Continue to Get Brighter
First introduced nearly a century ago, Raman spectroscopy and imaging methods continue to evolve through the development of new technologies and techniques. Spurred by the passage of state legislation last fall, the Southern California Coastal Water Research Project issued a methodology for monitoring microplastics in drinking water. The California regulation was the first of its kind in the U.S. to...
Spectroscopy Method Measures Both Terahertz, Raman Fingerprint Regions
TOKYO, March 17, 2022 — A Raman spectroscopy technique called dual-detection impulsive vibrational spectroscopy (DIVS) by its developers at the University of Tokyo allows two types of vibrational signals to be measured concurrently. DIVS enables broadband detection over...
Protocol Aims to Standardize Raman Spectral Analysis
JENA, Germany, Dec. 23, 2021 — Artificial intelligence (AI) is used increasingly to process and analyze data collected through Raman spectroscopy. Chemometric techniques, which are data-driven and include spectral processing and statistical analysis, can be used to detect and...
Photonics Offers Clues to the Future of Forensics
Dec 22, 2021 — Spectroscopy and other photonics technologies have long been of interest in criminal forensics — the use of analytical tools and tests to reveal unseen clues during a criminal investigation. Unlike some methods of chemical testing, photonics draws...
Raman Spectroscopy and Machine Learning Team Up to Predict Immunotherapy Response in Patients
BALTIMORE, Oct. 21, 2021 — Using Raman spectroscopy and machine learning, a team at Johns Hopkins University developed a noninvasive technique to assess how cancer patients will respond to immunotherapy. The researchers used Raman spectroscopy to map the biochemical...
Photon-Phonon Combination Will Enable Multi-Technique Spectroscopy Advances
NEW YORK, Oct. 14, 2021 — City College of New York (CCNY) researchers have demonstrated the ability to combine topological photons with lattice vibrations, or phonons, to manipulate their propagation in a robust and controllable way. The researchers made the photon-phonon...
