【摘要】 本文主要研究葡萄糖、葡萄糖氧化酶(GOD)以及两者的混合溶液的法拉第磁致旋光效应,为基于法拉第旋光效应的葡萄糖传感器提供了理论依据,研究介质的旋光特性,可以更好地提升光电传感器的性能,更广泛地应用光电传感器。在法拉第磁致旋光效应中,当介质处于磁场中时,平面偏振光透过该介质时,偏振面会旋转一个角度。将不同浓度的溶液置于磁场中,使用532 nm的激光器,激光通过起偏器光变成了平面偏振光,使平面偏振光透过溶液和检偏器,记录通过检偏器的光强并根据马吕斯定律计算旋光角。实验发现,随着磁感应强度的增加,旋光角与磁感应强度呈线性增加关系;随着溶液浓度的增加,溶液的旋光角也随之增加,磁场对低浓度溶液的旋光角影响更大。可以建立线性关系表示浓度和旋光角的关系。更多还原

【Abstract】 This article mainly studies the Faraday magneto-optical rotation effect of glucose, glucose oxidase(GOD) and the mixed solution of the two, which provides a theoretical basis for glucose sensors based on the Faraday optical rotation effect.Studying the optical rotation characteristics of the medium can better improve the performance of the photoelectric sensor and apply the photoelectric sensor more widely.In the Faraday magneto-optical rotation effect, when a medium is in a magnetic field, when plane-polarized light passes through the medium, the plane of polarization will rotate by an angle.Place solutions of different concentrations in a magnetic field and use a 532 nm laser.The laser light passes through the polarizer into plane-polarized light.The plane-polarized light passes through the solution and the analyzer.The intensity of the light passing through the analyzer is recorded according to the Marius′ law calculates the angle of rotation.Experiments have found that with the increase of magnetic induction intensity, the optical rotation angle and magnetic induction intensity increase linearly; with the increase of solution concentration, the optical rotation angle of the solution also increases, and the magnetic field has a greater influence on the optical rotation angle of low-concentration solutions.A linear relationship can be established to indicate the relationship between concentration and optical rotation angle.更多还原
