Paper Abstract

In this paper, we propose a novel lab-on-a-chip with an integrated spectrometer that uses a single, sensitive off-chip photomultiplier tube (PMT) for detection and the motion of fluorescent cells or other analytes in a microchannel to generate a signal that is equivalent to a time-dependent scan of the spectrum. The excitation light from off-chip lasers is carried to the channel by integrated waveguides and integrated lenses capture and focus the fluorescence into an optical waveguide that carries the fluorescent to the chip edge and into the fiber-coupled PMT. All elements can be fabricated in a single transparent layer of SU-8 or another polymer using standard microfabrication methods.
