    • A method and system for the detection of a target nucleic acid in a sample solution. The target nucleic acid comprises a first and a second end sequence, one of the end sequences being a 5' end sequence and the other end sequence being a 3' end sequence. The method comprises: (a) attaching to a solid surface a first oligonucleotide probe, at least a portion of which is complementary to the first end sequence of the target nucleic acid; (b) contacting the solid surface with the sample solution, thereby allowing the first probe to bind the target nucleic acid; (c) providing a second semiconductor nanoparticle to which has been attached a second oligonucleotide probe, at least a portion of which is complementary to the second end sequence of the target nucleic acid; (d) contacting the solid surface of step (b) with the second nanoparticle, thereby allowing the second probe to bind the bound target nucleic acid; (e) providing a first semiconductor nanoparticle to which has been attached the first oligonucleotide probe and pre-incubating the first nanoparticle with the target nucleic acid, thereby allowing the first probe to bind the target nucleic acid; (f) contacting the solid surface of step (d) with the pre-incubated first nanoparticle, thereby allowing the target nucleic acid bound to the first probe to bind the second probe on the second nanoparticle; and (g) detecting the presence of the nanoparticles on the solid surface, thereby detecting the target nucleic acid.

    • The present invention generally relates to nanotechnology and sub-microelectronic circuitry, as well as associated methods and devices, for example, nanoscale wire devices and methods for use in determining nucleic acids or other analytes suspected to be present in a sample (for example, their presence and/or dynamical information), e.g., at the single molecule level. For example, a nanoscale wire device can be used in some cases to detect single base mismatches within a nucleic acid (e.g., by determining association and/or dissociation rates). In one aspect, dynamical information such as a binding constant, an association rate, and/or a dissociation rate, can be determined between a nucleic acid or other analyte, and a binding partner immobilized relative to a nanoscale wire. In some cases, the nanoscale wire includes a first portion comprising a metal-semiconductor compound, and a second portion that does not include a metal-semiconductor compound. The binding partner, in some embodiments, is immobilized relative to at least the second portion of the nanoscale wire, and the size of the second portion of the nanoscale wire may be minimized and/or controlled in some instances. Articles and devices of size greater than the nanoscale are also included in certain embodiments. Still other aspects of the invention include assays, sensors, kits, and/or other devices that include such nanoscale wires, methods of making and/or using such nanoscale wires, or the like.
    • 本发明一般涉及纳米技术和亚微电子电路以及相关的方法和装置,例如纳米级线装置和用于确定疑似存在于样品中的核酸或其他分析物的方法(例如它们的 存在和/或动态信息),例如在单分子水平。 例如,在一些情况下可以使用纳米级线装置来检测核酸内的单碱基错配(例如通过确定缔合和/或解离速率)。 在一个方面,可以在核酸或其他分析物与相对于纳米线固定的结合配偶体之间确定动力学信息,例如结合常数,结合速率和/或解离速率。 在一些情况下,纳米级线包括包含金属半导体化合物的第一部分和不包含金属半导体化合物的第二部分。 在一些实施方案中,结合配偶体相对于纳米线的至少第二部分固定,并且在一些情况下纳米线的第二部分的尺寸可以被最小化和/或控制。 尺寸大于纳米级的制品和器件也包括在某些实施方案中。 本发明的其他方面包括分析,传感器,套件和/或包括这种纳米线的其他装置,制造和/或使用这种纳米线的方法等。

    • The present invention generally relates to nanobioelectronics and, in some cases, to circuits comprising nanoelectronic elements, such as nanotubes and/or nanowires, and biological components, such as neurons. In one aspect, cells, such as neurons, are positioned in electrical communication with one or more nanoscale wires. The nanoscale wires may be used to stimulate the cells, and/or determine an electrical condition of the cells. More than one nanoscale wire may be positioned in electrical communication with the cell, for example, in distinct regions of the cell. However, the nanoscale wires may be positioned such that they are relatively close together, for example, spaced apart by no more than about 200 nm. The nanoscale wires may be disposed on a substrate, for example, between electrodes, and the cells may be adhered to the substrate, for example, using cell adhesion factors such as polylysine. Also provided in other aspects of the invention are methods for making and using such devices, kits for using the same, and the like.
    • 本发明一般涉及纳米生物电子学,并且在一些情况下涉及包含纳米电子元件(例如纳米管和/或纳米线)和生物组分(例如神经元)的电路。 在一个方面,诸如神经元的细胞被定位成与一个或多个纳米级导线电连通。 纳米级线可用于刺激细胞,和/或确定细胞的电状况。 例如,在电池的不同区域中,可以放置多于一根的纳米级电线与电池电连通。 然而,纳米级线材可以定位成使得它们相对靠近在一起,例如间隔不超过约200nm。 纳米级线可以设置在例如电极之间的基板上,并且例如可以使用细胞粘附因子例如聚赖氨酸将细胞粘附到基板。 在本发明的其他方面也提供了制造和使用这种装置的方法,使用它们的试剂盒等。
