    • The invention relates to the fabrication and use of biosensors comprising a plurality of optical fibers each fiber having attached to its "sensor end" biological "binding partners" (molecules that specifically bind other molecules to form a binding complex such as antibody-antigen, lectin-carbohydrate, nucleic acid-nucleic acid, biotin-avidin, etc.). The biosensor preferably bears two or more different species of biological binding partner. The sensor is fabricated by providing a plurality of groups of optical fibers. Each group is treated as a batch to attach a different species of biological binding partner to the sensor ends of the fibers comprising that bundle. Each fiber, or group of fibers within a bundle, may be uniquely identified so that the fibers, or group of fibers, when later combined in an array of different fibers, can be discretely addressed. Fibers or groups of fibers are then selected and discretely separated from different bundles. The discretely separated fibers are then combined at their sensor ends to produce a high density sensor array of fibers capable of assaying simultaneously the binding of components of a test sample to the various binding partners on the different fibers of the sensor array. The transmission ends of the optical fibers are then discretely addressed to detectors--such as a multiplicity of optical sensors. An optical signal, produced by binding of the binding partner to its substrate to form a binding complex, is conducted through the optical fiber or group of fibers to a detector for each discrete test. By examining the addressed transmission ends of fibers, or groups of fibers, the addressed transmission ends can transmit unique patterns assisting in rapid sample identification by the sensor.
    • 本发明涉及生物传感器的制造和使用,该生物传感器包括多个光纤,每个光纤各自连接到其“传感器端”生物“结合伙伴”(特异性结合其他分子以形成结合复合物如抗体抗原,凝集素 碳水化合物,核酸 - 核酸,生物素 - 抗生物素蛋白等)。 生物传感器优选具有两种或更多种不同种类的生物结合配偶体。 通过提供多组光纤来制造传感器。 将每组作为批次处理以将不同种类的生物结合配偶体附着到包含该束的纤维的传感器末端。 束内的每个纤维或一组纤维可以被唯一地识别,使得当稍后组合在不同纤维阵列中时,纤维或纤维组可以离散地寻址。 然后选择纤维或纤维组,并从不同的束离散分离。 然后将离散分离的纤维在其传感器端组合以产生能够同时测定测试样品的组分与传感器阵列的不同纤维上的各种结合配偶体的结合的高密度纤维传感器阵列。 然后将光纤的传输端离散地寻址到诸如多个光学传感器的检测器。 通过将结合配偶体与其底物结合以形成结合复合物产生的光学信号通过光纤或纤维组进行到用于每个离散测试的检测器。 通过检查光纤或光纤组的所寻址的传输端,所寻址的传输结束可以传输有助于传感器快速采样识别的独特模式。
