    Abstract: Biological cells in a liquid suspension are counted in an automated cell counter that focuses an image of the suspension on a digital imaging sensor that contains at least 4,000,000 pixels each having an area of 2×2 μm or less and that images a field of view of at least 3 mm2. The sensor enables the counter to compress the optical components into an optical path of less than 20 cm in height when arranged vertically with no changes in direction of the optical path as a whole, and the entire instrument has a footprint of less than 300 cm2. Activation of the light source, automated focusing of the sensor image, and digital cell counting are all initiated by the simple insertion of the sample holder into the instrument. The suspension is placed in a sample chamber in the form of a slide that is shaped to ensure proper orientation of the slide in the cell counter.

    Abstract: A system for performing high-speed, high-resolution imaging cytometry includes a scanning region that is illuminated by light including at least first and second wavelength bands. The system also includes a cell transport mechanism that transports a cell through the scanning region such that the cell is illuminated. The system further includes a set of at least one linear light sensor, and an optical system that selectively directs light emitted from the cell to two portions of the linear light sensor set such that emitted light in a third wavelength band is primarily directed to a first portion of the linear light sensor set, and emitted light in a fourth wavelength band is primarily directed to a second portion of the linear light sensor set. The system repeatedly takes readings of light falling on the linear light sensor set while the cell is transported through the scanning region.

    Abstract: Analyte arrays such as solutes in a slab-shaped gel following electrophoresis, and particularly arrays that are in excess of 3 cm square and up to 25 cm square and higher, are imaged at distances of 5 cm or less by either forming sub-images of the entire array and stitching together the sub-images by computer-based stitching technology, or by using an array of thin-film photoresponsive elements that is coextensive with the analyte array to form a single image of the array.
