    • The present invention relates to the field of film materials for biosensors, in particular to a film for biosensors and a preparation method. Provided is an organosilicon polymer, the raw materials thereof comprising the following components: at least one active organosiloxane, at least one curing agent, at least one optional hydrophilic copolymer and at least one optional regulator and/or filling. The membrane prepared from the provided organosilicon polymer has outstanding oxygen permeability and is adjustable in water absorption rate, and can put regulation and restriction on the diffusion of analytes (e.g. glucose) and interferents (e.g. acetaminophen). Meanwhile, the provided organosilicon polymer film also has indispensable physical strength and superior biocompatibility, and can serve as a multifunctional polymer film material for biosensors, such as anti-interference layer, analyte regulating layer and biocompatible layer.
    • 本发明涉及用于生物传感器的薄膜材料领域,特别涉及用于生物传感器的薄膜和制备方法。 提供一种有机硅聚合物,其原料包含以下组分:至少一种活性有机硅氧烷,至少一种固化剂,至少一种任选的亲水共聚物和至少一种任选的调节剂和/或填充物。 由所提供的有机硅聚合物制备的膜具有优异的透氧性,并且在吸水率方面是可调节的,并且可以调节和限制分析物(例如葡萄糖)和干扰物(例如对乙酰氨基酚)的扩散。 同时,提供的有机硅聚合物膜也具有不可或缺的物理强度和优异的生物相容性,可作为生物传感器的多功能聚合物膜材料,如抗干扰层,分析物调节层和生物相容层。
