Chemists use gold nanoparticles to help medics detect a marker molecule for prostate cancer

Duncan Graham of the Centre for Molecular Nanometrology at the University of Strathclyde, and colleagues in the Division of Cancer Sciences and Molecular Pathology at the University of Glasgow, have combined surface-enhanced resonance Raman scattering (SERRS) spectroscopy with a biological test called ELISA to improve accuracy, lower detection limits and make testing for early prostate cancer less invasive and less expensive.1
