    • Disclosed is a method for fabricating biosensors, using hydrophilic polyurethane. Bio-active reagents, including enzymes, antibodies, antigens, cells and receptors, are mixed with hydrophilic polyurethane and the mixture is directly coated over a signal transducer to form a sensing film which serves as a signal detector. The method using hydrophilic polyurethane allows the simplification of the fabrication of biosensors without conducting complicated chemical reactions and washing steps, such as crosslinking. The bio-active reagent entrapped within the hydrophilic polyurethane film can retains its high activity for an extended period of time and the intrinsic potentiometric response of the underlying ion-selective polymeric membrane is not affected by the bio-active reagent immobilized polyurethane film coated on its sensing surface. Therefore, the biosensors are superior in specificity, selectivity, and stability. Also, the adoption of solid-state type electrodes by virtue of the direct immobilization of the bio-active reagents allows the biosensors to be miniaturized, offering the advantages of the detection of small quantities of samples and mass production for low cost.
    • 公开了使用亲水性聚氨酯制造生物传感器的方法。 将生物活性试剂(包括酶,抗体,抗原,细胞和受体)与亲水性聚氨酯混合,并将混合物直接涂覆在信号转换器上以形成用作信号检测器的感测膜。 使用亲水性聚氨酯的方法可以简化生物传感器的制造,而无需进行复杂的化学反应和清洗步骤,如交联。 截留在亲水性聚氨酯膜内的生物活性试剂可以长时间保持其高活性,并且下面的离子选择性聚合物膜的固有电位响应不受其上涂覆有生物活性试剂固定的聚氨酯膜 感应表面。 因此,生物传感器在特异性,选择性和稳定性方面优越。 此外,通过直接固定生物活性试剂而采用固态电极使生物传感器小型化,提供了检测少量样品和低成本大规模生产的优点。
