Microfluidic Detector Illustrated Concept (image) University of California - Santa Barbara Share Print E-Mail Caption This is an illustrated concept of the device's microscale free-surface microfluidic channel as it concentrates vapor molecules that bind to nanoparticles inside a chamber. Through surface-enhanced Raman spectroscopy, a laser beam detects the nanoparticles, which amplify a spectral signature of the detected molecules.
