    摘要： The present methods and apparatus concern the detection and/or identification of target analytes using probe molecules. In various embodiments of the invention, the probes or analytes are attached to one or more cantilevers. Binding of a probe to an analyte results in deflection of the cantilever, detected by a detection unit. A counterbalancing force may be applied to restore the cantilever to its original position. The counterbalancing force may be magnetic, electrical or radiative. The detection unit and the mechanism generating the counterbalancing force may be operably coupled to an information processing and control unit, such as a computer. The computer may regulate a feedback loop that maintains the cantilever in a fixed position by balancing the deflecting force and the counterbalancing force. The concentration of analytes in a sample may be determined from the magnitude of the counterbalancing force required to maintain the cantilever in a fixed position.

    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.

    摘要： The methods and apparatus disclosed herein concern nucleic acid sequencing by enhanced Raman spectroscopy. In certain embodiments of the invention, nucleotides are covalently attached to Raman labels before incorporation into a nucleic acid. In other embodiments, unlabeled nucleic acids are used. Exonuclease treatment of the nucleic acid results in the release of labeled or unlabeled nucleotides that are detected by Raman spectroscopy. In alternative embodiments of the invention, nucleotides released from a nucleic acid by exonuclease treatment are covalently cross-linked to nanoparticles and detected by surface enhanced Raman spectroscopy (SERS), surface enhanced resonance Raman spectroscopy (SERRS) and/or coherent anti-Stokes Raman spectroscopy (CARS). Other embodiments of the invention concern apparatus for nucleic acid sequencing.
