    • In a recognition complex system, nucleic acid ligands comprising random DNA sequences are operatively coupled to an organic semiconductor and distributed so as to form an array of recognition complexes. When an unknown chemical or biological analyte is applied to the array, the electrical and/or photochemical properties of one or more of the recognition complexes are altered upon binding of the nucleic acid ligand to the analyte. The degree to which the electrical and/or photochemical properties change is a function of the affinity of the nucleic acid ligand sequence for the analyte. The electrical and photochemical changes associated with the array, as a whole, can be used as a unique signature to identify the analyte. In certain embodiments, an iterative process of selection and amplification of nucleic acid ligands that bind to the analyte can be used to generate a new array with greater affinity and specificity for a target analyte, or to produce one or more nucleic acid ligands with high binding affinity for an analyte. The present invention also provides methods for preparing nucleic acid ligands that bind with high affinity to an analyte and using such nucleic acid ligands to neutralize the analyte.
    • 在识别复合体系中,包含随机DNA序列的核酸配体可操作地偶联到有机半导体上,并分布以形成识别复合物的阵列。 当将未知的化学或生物分析物施加到阵列时,一个或多个识别复合物的电和/或光化学性质在核酸配体与分析物结合时被改变。 电和/或光化学性质变化的程度是核酸配体序列对分析物的亲和力的函数。 与阵列相关联的电学和光化学变化作为一个整体,可以用作识别分析物的独特标记。 在某些实施方案中,结合分析物的核酸配体的选择和扩增的迭代过程可用于产生对靶分析物具有更大亲和性和特异性的新阵列,或产生具有高结合力的一个或多个核酸配体 对分析物的亲和力。 本发明还提供了制备以高亲和力结合分析物并使用这种核酸配体中和分析物的核酸配体的方法。

    • An apparatus and method for immunomagnetic separation and concentration of target biological materials is disclosed. The immunomagnetic separation is performed by a magnetic flow cell, or filter block, as part of an automated mostly continuous immunomagnetic assay system. The magnetic flow cell has two bundles of ferromagnetic rods or pins positioned inside an internal chamber so that a fluid sample flowing through the flow cell passes through the pins. A pair of cobalt magnets flank the flow cell so that the pins concentrate and sufficiently increase the magnetic fields so that even nanometer size magnetic beads can be captured. The overall system combines a reaction subsystem for reacting coated magnetic beads with a sample, a collection subsystem for capturing magnetic beads, a rinsing subsystem for removing debris and a filtering subsystem for removing captured magnetic beads from the collection subsystem. The new magnetic flow filter is the key component for the collection and filtering subsystems.
