Using multiple laser beams and Raman spectroscopy, researchers at the Universities of Nottingham and Glasgow have designed and built a new instrument that could help scientists learn more about how infections take hold and how antibiotic-resistant bacterial biofilms are formed. The instrument uses holographic optical traps to form connections between multiple human immune cells. Changes in the cell interactions are measured over time using Raman spectroscopy. To enable optical trapping and Raman spectroscopy to be used simultaneously at many sample points, the research team combined a...Read full articleRelated content from Photonics MediaARTICLESSpectroscopy Technique Widens Spectra for Measuring Molecular StructureResearchers at the University of Tokyo have combined two current spectroscopy techniques — infrared (IR) absorption and Raman scattering spectrometry — to create complementary vibrational...Photonics Spectra December 2019 IssueRaman Scattering Helps Ensure Safety of Stem Cell TherapiesA research team at Rutgers University has developed a biosensor technology that could benefit applications for the treatment of neurological disorders through stem cell therapy.
