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 MediaARTICLESProtocol Aims to Standardize Raman Spectral AnalysisArtificial intelligence (AI) is used increasingly to process and analyze data collected through Raman spectroscopy.
