    摘要: An embodiment of the invention relates to a device for detecting an analyte in a sample. The device comprises a fluidic network and an integrated circuitry component. The fluidic network comprises multiple zones such as a sample zone, a cleaning zone and a detection zone. The fluidic network contains a magnetic particle and/or a signal particle. A sample containing an analyte is introduced, and the analyte interacts with the magnetic particle and/or the signal particle through affinity agents. A microcoil array or a mechanically movable permanent magnet is functionally coupled to the fluidic network, which are activatable to generate a magnetic field within a portion of the fluidic network, and move the magnetic particle from the sample zone to the detection zone. A detection element is present which detects optical or electrical signals from the signal particle, thus indicating the presence of the analyte.

    摘要: The present methods, compositions and systems are concerned with biomolecule 130 detection, identification and/or quantification by rolling circle amplification (RCA) and Raman detection. In particular embodiments of the invention, the RCA is exponential RCA or linear RCA. In some embodiments of the invention, the Raman detection is SERS or SERRS. The circular DNA template 150, 210, 310 to be amplified may comprise one or more polythymidine 320 residues, resulting in amplification products 170, 230, 250, 330, 410 containing multiple polyadenylate 340, 420 residues. The polyadenylates 340, 420 may be directly detected by Raman detection. Alternatively, one or more Raman labels may be incorporated into the amplification products 170, 230, 250, 330, 410 to facilitate Raman detection. Because of the amplification produced by LRCA or ERCA and the enhanced Raman signal produced by multiple polyadenylates 340, 420 and/or Raman labels, detection of single copy biomolecules 130 is feasible using the disclosed methods, compositions and/or systems.

    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: Briefly, in accordance with one embodiment of the invention, the intensity of the signals from surface enhanced Raman spectroscopy may be increased by using lithium chloride as an enhancer to activate a metallic structure used for surface enhanced Raman spectroscopy. The increased signal intensity may allow surface enhanced Raman spectroscopy to be utilized to detect individual analytes such as nucleotides, for example in DNA sequencing without requiring a dye or radioactive label.
