Native fluorescence spectroscopy on a chip for pathogen detection

 

Our compact, low-cost pathogen detection platform combines a fluidic channel with a chip-size, distributed spectrometer that is optimized to record fluorescence spectra from moving analytes. Large-volume, continuous fluorescence excitation is achieved by incorporating the fluidic channel into an anti-resonance waveguide that accommodates either laser diodes or LEDs. Simultaneously monitoring total intensity and spectrally-resolved emission yields accurate spectra for pathogen discrimination. System operation and pathogen detection will be demonstrated by video.
