Abstract

Embodiments are directed to an apparatus that includes a fluidic structure and optical components. The fluidic structure includes a transparent channel through which objects in an analyte fluid can travel along respective paths during operation of the apparatus. The optical components are configured to provide measurement light to the objects traveling through the transparent channel. The fluidic structure is configured to reversibly engage with a host structure. The host structure includes a source of the measurement light and electronics to receive and process output light emanating from the objects traveling in the channel. The fluidic structure makes an air-tight seal when engaged with the host structure.
