    摘要: The present invention relates to a device (100) and a method for optically controlling a chemical reaction in a reaction chamber (149) comprising a reagent fluid (114). In a preferred embodiment, the chemical reaction comprises a nucleic acid sequencing on a wiregrid. Based on strong optical confinement of excitation light (110) and of cleavage light (112), the sequencing reaction can be read-out. Stepwise sequencing is achieved by using nucleotides with optically cleavable blocking moieties. After read-out the built in nucleotide is deblocked by cleavage light through the same substrate. This ensures that only bound nucleotides will be unblocked. In order to avoid overheating by cleavage light, the reagent fluid is circulated along the surface of the substrate (101).

    摘要: The present invention provides compositions and methods to facilitate the identification of compounds that are capable of interacting with a biological macromolecule of interest. In one aspect, a composition is provided that comprises an array of one or more types of chemical compounds attached to a solid support, wherein the density of the array of compounds is at least 1000 spots per cm2. In particularly preferred embodiments, these compounds are attached to the solid support through a covalent interaction. In general, these inventive arrays are generated by: (1) providing a solid support, wherein said solid support is functionalized with a selected chemical moiety capable of interacting with a desired chemical compound to form an attachment; (2) providing one or more solutions of one or more types of compounds to be attached to the solid support; and (3) delivering said one or more types of compounds to the solid support, whereby an array is formed and the array of compounds has a density of at least 1000 spots per cm2. In another aspect, the present invention provides methods for utilizing these arrays to identify small molecule partners for biological macromolecules of interest comprising: (1) providing an array of compounds, wherein the array has a density of at least 1000 spots per cm2; (2) contacting the array with one of more types of biological macromolecules of interest; and (3) determining the interaction of specific small molecule-biological macromolecule partners.
