Abstract
(EN) The invention relates to a solid-state quantum dot sensor as well as a preparation method and application thereof. Quantum dots are embedded into a polymer matrix formed by perfluorosulfonic acid andpolyvinyl alcohol to form the solid-state quantum dot sensor. Glucose oxidase is embedded into the solid-state quantum dot sensor to generate a solid-state quantum dot glucose sensor. According to thesolid-state quantum dot sensor provided by the invention, the quantum dots and the glucose oxidase are stable in the sensor by specifically selecting a polymer matrix, when the sensor is exposed on atest sample, rapid response can be realized, and the detection efficiency and the sensitivity are improved.
(ZH) 本发明涉及一种固态量子点传感器及其制备方法与用途。所述量子点包埋于由全氟磺酸和聚乙烯醇组成的聚合物基质中以形成固态量子点传感器。将葡萄糖氧化酶包埋到所述固态量子点传感器中产生固态量子点葡萄糖传感器。在本发明提供的固态量子点传感器中，通过特异性选择聚合物基质使量子点和葡萄糖氧化酶在传感器中稳定，当传感器暴露于测试样时，可以快速响应，提高检测效率与灵敏度。
