    摘要: The methods, apparatus and compositions disclosed herein concern the detection, identification and/or sequencing of biomolecules, such as nucleic acids or proteins. In certain embodiments of the invention, coded probes comprising a probe molecule attached to one or more nanobarcodes may be allowed to bind to one or more target molecules. After binding and separation from unbound coded probes, the bound coded probes may be aligned on a surface and analyzed by scanning probe microscopy. The nanobarcodes may be any molecule or complex that is distinguishable by SPM, such as carbon nanotubes, fullerenes, submicrometer metallic barcodes, nanoparticles or quantum dots. Where the probes are oligonucleotides, adjacent coded probes hybridized to a target nucleic acid may be ligated together before alignment and SPM analysis. Compositions comprising coded probes are also disclosed herein. Systems for biomolecule analysis may comprise an SPM instrument and at least one coded probe attached to a surface.

    摘要: A method for determining a nucleotide sequence of a nucleic acid is provided that includes contacting the nucleic acid with a series of labeled oligonucleotides for binding to the nucleic acid, wherein each labeled oligonucleotide includes a known nucleotide sequence and a molecular nanocode. The nanocode of an isolated labeled oligonucleotides that binds to the nucleic acid is then detected using SPM. Nanocodes of the present invention in certain aspects include detectable features beyond the arrangement of tags that encode information about the barcoded object, which assist in detecting the tags that encode information about the barcoded object. The detectable features include structures of a nanocode or associated with a nanocode, referred to herein as detectable feature tags, for error checking/error-correction, encryption, and data reduction/compression.

    摘要: The present methods and apparatus concern nucleic acid sequencing by incorporation of nucleotides into nucleic acid strands. The incorporation of nucleotides is detected by changes in the mass and/or surface stress of the structure. In some embodiments of the invention, the structure comprises one or more nanoscale or microscale cantilevers. In certain embodiments of the invention, each different type of nucleotide is distinguishably labeled with a bulky group and each incorporated nucleotide is identified by the changes in mass and/or surface stress of the structure upon incorporation of the nucleotide. In alternative embodiments of the invention only one type of nucleotide is exposed at a time to the nucleic acids. Changes in the properties of the structure may be detected by a variety of methods, such as piezoelectric detection, shifts in resonant frequency of the structure, and/or position sensitive photodetection.
