Previewing the Biomedical Raman Imaging 2023 Conference
May 11th 2023Biomedical Raman imaging is growing in the biomedical space, where technical advances and new information processing tools and techniques aim to propel the field into the future. An upcoming conference in Atlanta, Georgia, will explore these developments while bringing scientists in this field together.
Raman Imaging Techniques Compared for Analysis of Zirconium Oxide Layer
May 10th 2023The article discusses a comparison of Raman imaging assessment methods for phase determination and stress analysis of zirconium oxide layers and their application in the development of zirconium alloys, especially for nuclear applications.
New Method for Interpreting Raman Spectroscopy Data in Biological Samples
May 2nd 2023Researchers have developed a new method for analyzing Raman spectroscopy data in biological samples using group- and basis-restricted non-negative matrix factorization (GBR-NMF) framework, providing a promising approach for interpreting Raman spectroscopy data in biological samples.
Detecting Blood on Interfering Substrates Using a Novel Raman Spectroscopy Method
April 6th 2023According to new research, two new Raman spectroscopy approaches, reducing a spectrum complexity (RSC) and multivariate curve resolution combined with the additions method (MCRAD), can detect bloodstains on a multitude of well-known substrates, with RSC proving to be the more effective technique.
A Fingerprint in a Fingerprint: Raman Spectral Analysis of Pharmaceutical Ingredients
March 1st 2023The significance of the smaller spectral region of the Raman spectrum, defined as the “fingerprint in the fingerprint” region, cannot be overstated when it comes to active pharmaceutical ingredient identity testing (API).
Differentiating Glycans by Surface-Enhanced Raman Spectroscopy
February 20th 2023Glycoproteins are becoming popular in the pharmaceutical industry, prompting the need for an effective spectroscopic technique that can differentiate them. SERS is one such technique ideal for glycan analysis for several key reasons, which are discussed here.
Raman Spectroscopy and Machine Learning-Based Optical Probe for Tuberculosis Diagnosis via Sputum
November 2nd 2022In the treatment of tuberculosis (TB), a contagious disease that causes 1.5 million deaths per year globally, early diagnosis is critical in order to control its spread. Unfortunately, standard tuberculosis diagnostic tests, such as sputum culture, can take days to weeks to yield results. In a recent paper, Ubaid Ullah of the Syed Babar Ali School of Science and Engineering in Pakistan and his colleagues demonstrate a quick, portable, easy-to-use, and non-invasive optical sensor based on sputum samples for tuberculosis detection using Raman spectroscopy to detect TB in a patient’s sputum supernatant. Ullah spoke to Spectroscopy about this sensor and its development.
Spectrometers in Wonderland: Shrinking, Shrinking, Shrinking
November 1st 2022In the past 20 years, spectrometers have shrunk dramatically in size, and this shrinking has been achieved with only modest performance reductions in sampling versatility, spectral range, spectral resolution, and signal-to-noise.
A Decade of Surface Enhanced Spatially Offset Raman Scattering (SESORS)
September 8th 2022Karen Faulds of the University of Strathclyde co-authored a paper where SESORS signals could be detected from nanotags at depths down to 48 mm for the first time using a handheld spatially offset Raman (SORS) instrument. She recently spoke to Spectroscopy about this and some of her other papers and the advances in the science that made them possible. Faulds is the 2022 recipient of the RSC Analytical Division Mid-Career Award. This interview is part of an ongoing series of interviews with the winners of awards that are presented at the annual SciX conference, which will be held this year from October 2 through October 7, in Covington, Kentucky.
