Fluidic flow cytometry devices and methods

Abstract

Devices, systems and methods facilitate analyzing, identifying and sorting particles in fluids, including cytometry devices and techniques. The described techniques can be used in a variety of applications such as in chemical or biological testing and diagnostic measurements. One exemplary flow cytometry device includes a channel that is capable of conducting a fluid containing at least one particle and also capable of allowing light be transmitted to and from the channel. The flow cytometry device also includes a lens that is positioned between the channel and a color filter. The lens directs at least a portion of light transmitted from the channel to the color filter. The color filter includes a plurality of zones, where each zone is adapted to allow transmission of only a particular spectral range of light. The flow cytometry device further includes a detector configured to receive the light that is transmitted through the color filter.
