Abstract:
A portable or wearable cytometer (10) that can be used at remote locations, such as in the field or at home. The flow cytometer (10) of the present invention may help improve the healthcare of many weak, sick or elderly people by providing early detection of infection. By detecting the infection early, the infection may be more readily treatable. In military applications, the portable cytometer (10) of the present invention may help save lives by providing early detection of infection due to biological agents.
Abstract:
An optical detection system for flow cytometry that uses two or more light sources (208,210) positioned laterally at different distances from the central axis (202) of the flow stream (50) for providing light through different parts of the flow stream (50). Byusing two or more light sources (208,210), the particle position can be detected, and the alignment and width of the core stream (160) can be monitored and controlled. In addition, the velocity and size of the particles can be more accurately determined than when only a single light source is used.
Abstract:
A multiplexed set of light sources having outputs of light with various wavelengths which are combined into one beam. The beam may impinge a particle in a flow channel of a cytometer. The light leaving the flow channel may be sensed by a detector and the light distinguished according to wavelength.
Abstract:
A fluid driving system for portable flow cytometers (10) or other portable devices that accept a less precise and less stable pressure source, and then adjusts the pressure in a closed-loop manner to maintain a constant, desired flow velocity. The fluid driving system may be used in portable or wearable cytometers (10) for use in remote locations, such as at home or in the field.

Abstract:
The present invention relates to a sensor comprising: a thermally isolated area on a substrate; a heating element proximate the thermally isolated area; a pair of conductors each having a portion adjacent a portion of the other; and a plurality of carbon nanotubes formed extending from one of the conductors to the other.
