Topic: Raman spectroscopy

This scientific discussion meeting asks which nanoscale optical sensing approaches can deliver affordable, information-rich healthcare measurements. Its focus is continuous biochemical monitoring beyond conventional physiological wearables and diagnostic sensors. The programme examines interferometric biomarker detection, surface-enhanced Raman assays, nanophotonic sensing and translation toward practical diagnostic tools, comparing modalities and their potential for use across healthcare settings. Jeremy Baumberg and Duncan Graham organize the meeting; programme participants include Selim Ünl

Raman spectroscopy is a powerful technique for identifying chemical species by probing their vibrational energy levels, offering exceptional specificity with a relatively simple setup involving a laser source, spectrometer, and microscope/probe. However, the high cost of Raman systems lacking modularity often limits exploratory research hindering broader adoption. To address the need for an affordable, modular microscopy platform for multimodal imaging, we present a customizable confocal Raman spectroscopy setup alongside an open-source acquisition software, ORM (Open Raman Microscopy) Control
