    摘要: Provided is an optical sensor including a support and a detection layer, wherein the detection layer includes: (a) a luminescent material wherein the luminescence intensity of the luminescent material varies as the amount of an analyte varies; (b) a reflective material having a highly efficient reflectance of the wavelengths of excitation and of emission of the luminescent material; and (c) a polymeric binder to support and hold together the luminescent material and the reflective material. Such an optical sensor can be advantageously used in the detection of gaseous, ionic, and nonionic analytes in highly scattering samples. Also provided are methods for the manufacture of such optical sensors.

    摘要: The invention provides a method of selecting a representational sample of nucleic acid sequences from a complex mixture. The method includes: (a) contacting a complex mixture of nucleic acids under conditions sufficient for hybridization with a population of capture probes complementary to one or more nucleic acids comprising a predetermined portion of the sequence collectively present in the complex mixture to form hybridization complexes of the one or more nucleic acids with the population of probes, the population of capture probes being attached to a solid support, and (b) removing unhybridized nucleic acids to select a representational sample of nucleic acids having a complexity of less than 10% but more than 0.001% of the complex mixture, wherein the representational sample comprises a nucleic acid copy having a proportion of each sequence in the copy relative to all other sequences in the copy substantially the same as the proportions of the sequences in the predetermined portion of one or more nucleic acids within the complex mixture. A method of selecting a representational sample of genomic sequences from a complete genome also is provided. The invention further provides a nucleic acid population that includes a representational sample having a complexity of less than 10% but more than 0.001% of a complex mixture, the representational sample comprising a nucleic acid copy having a proportion of each sequence in the copy relative to all other sequences in the copy substantially the same as the proportions of sequences in a predetermined portion of a sequence collectively present in one or more nucleic acids within the complex mixture.
