Investigating Food Purity Using Raman Spectroscopy Combined with Machine Learning

February 11, 2022

Determining the quality of the food we consume is important not just for reasons of safety, but for verifying authenticity as well. Changmou Xu, a Research Associate Professor at the University of Nebraska-Lincoln (UNL), and his colleagues have been exploring methods for food analysis that are rapid but do not harm the environment or the analysts.

Quantitative Analysis Using Surface-enhanced Raman Scattering (SERS): Roy Goodacre, the 2021 winner of the Charles Mann Award for Applied Raman Spectroscopy

September 02, 2021

Roy Goodacre, a professor of biological chemistry at the University of Liverpool in the United Kingdom, first used SERS to achieve whole-organism fingerprinting of bacteria and then explored SERS in a variety of other applications, including within biotechnology, disease diagnostics, quantitative detection, imaging, food security, and more. Goodacre is the 2021 winner of the Charles Mann Award for Applied Raman Spectroscopy. This interview is part of an ongoing series of interviews with the winners of awards that are presented at the annual SciX conference.

Optical Modeling and Detection of Infrared and Other Spectra

July 12, 2019

Timothy J. Johnson and Tanya L. Myers, the 2019 winners of the Applied Spectroscopy William F. Meggers Award, have been exploring novel methods using infrared (IR) and visible reflectance spectroscopies for identification of target chemicals through derivation of the n and k optical constants. For their winning paper, Johnson and Myers created a spectroscopic library of 57 liquids for which they measured the complex refractive index, data that can be used for optical modeling and other purposes. They shared some of the details of their work with Spectroscopy.

New Spectroscopic Techniques Aid in Tissue Engineering

March 13, 2019

Advanced techniques in tissue engineering hold promise to those who suffer from damage to or degeneration of joint cartilage. But some challenges exist for tissue engineers to gain a better understanding of the development of these constructs and their mechanical properties. Nancy Pleshko, a professor of Bioengineering at Temple University (Philadelphia, Pennsylvania) has been studying the use of Fourier-transform–infrared imaging spectroscopy (FT-IRIS) as well as near-infrared (NIR) spectroscopy to explore the ways in which these techniques can aid in the development of replacement tissue. We spoke to her about her research and findings.
