    摘要： Methods and apparatus for detecting polynucleotide hybridization in luminescence-based assays. The methods may include (1) contacting a sample polynucleotide with a reference polynucleotide at an assay site, where at least one of the polynucleotides is capable of emitting luminescence, (2) illuminating the assay site with light capable of stimulating such luminescence, (3) detecting light transmitted from the assay site, and (4) deriving information relating to the extent of hybridization between the sample and reference polynucleotides based on the detected light. The methods may further include (1) illuminating with and/or detecting polarized light, (2) deriving information relating to the sequence of the sample polynucleotide from the extent of hybridization, and (3) converting the light to a signal and distinguishing between a portion of the signal attributable to luminescence and a portion attributable to background.

    摘要： Apparatus and methods for combining multiple modes and methods of optical detection, postprocessing, and/or feedback loops in bioanalytical measurements. The methods may include (1) positioning a composition at an examination site in a multi-mode instrument; (2) detecting light transmitted form the composition using the multi-mode instrument in a first optical measurement mode; (3) detecting light transmitted from the composition using the multi-mode instrument in a second optical measurement mode, the second mode being different than the first mode; and (4) computing a quantity related to a property of the composition using the light detected in at least one of the optical measurement modes. These steps may be performed on one or more samples, simultaneously and/or sequentially. The quantity may relate to photoluminescence, chemiluminescence, absorption, and/or scattering, among others.

    摘要： A reflective light imaging system for use in high-throughput screening of samples disposed in multiple-well plates. The system can include a set of mirrors and lenses. The first mirror has a central aperture through which light from the object passes. The first mirror has a concave reflective surface that faces the image plane. The next element is a second mirror with a convex reflective surface. The system can include an aberration corrective system positioned between the second mirror and the image plane, and an optical sensor near the image plane. Light from an object passes through the central aperture of the first mirror and is reflected off the convex surface of the second mirror. The light then strikes the reflective surface of the first mirror. The light from the first mirror is then collected by the aberration correction system and transmitted toward the image plane.
