Abstract
The present invention provides a microfluidic system, device, and kit for particle analysis. In one example, the device includes a fluid channel for spacing the particles, an excitation waveguide to guide an excitation beam from a source to the fluid channel, and an excitation lens to focus the excitation beam to a width less than the spacing of the particles in the fluid channel. The device also includes a detection lens to guide light transmitted from the channel along a number of paths, axial and scatter light waveguide to receive light guided by the detection lens, a detector to receive transmitted light from the waveguides and generate a detection signal, and a processor configured to receive the detection signal and determine characteristic features of each of the particles based on the detection signal.
