    Abstract: Small particles 1, for example 5 mu m diameter microspheres or cells, within, and moving with, a fluid 2, normally water, that is flowing within microfluidic channels 3 within a radiation-transparent substrate 4, typically molded PDMS clear plastic, are selectively manipulated, normally by being pushed with optical pressures forces, with a laser light switching beam 5, preferably as arises from VCSELs operating in Laguerre-Gaussian mode, at branching junctions, such as an "X", in the microfluidic channels 3 so as to enter into selected downstream branches OUTPUT 1, OUPUT 2, thereby realizing switching and sorting of particles 1, including in parallel. Transport of the small particles 1 thus transpires by microfluidics while manipulation in the manner of optical tweezers arises either from pushing due to optical scattering force, or from pulling due to an attractive optical gradient force. Whether pushed or pulled, the particles within the flowing fluid may be optically sensed, and highly-parallel. Low-cost, cell- and particle-analysis devices efficiently realized, including as integrated on bio-chips.

    Abstract: This invention provides rotors and methods of precisely metering a sample fluid and mixing the sample with a reagent. The rotors have a metering tube of defined volume that fills until sample flow is stopped by surface tension of a meniscus at a capillarity port, while excess sample is stripped from the metering tube inlet by centripetal force of the spinning rotor. By spinning the rotor at a higher speed, a reagent can be forced from a reagent chamber to contact the meniscus, breaking the surface tension and allowing the metered sample to mix with the reagent.

    Abstract: The invention provides imaging apparatus and methods useful for obtaining a high resolution image of a sample at rapid scan rates. A rectangular detector array having a horizontal dimension that is longer than the vertical dimension can be used along with imaging optics positioned to direct a rectangular image of a portion of a sample to the rectangular detector array. A scanning device can be configured to scan the sample in a scan-axis dimension, wherein the vertical dimension for the rectangular detector array and the shorter of the two rectangular dimensions for the image are in the scan-axis dimension, and wherein the vertical dimension for the rectangular detector array is short enough to achieve confocality in a single axis.
