精品文档---下载后可任意编辑基于 MHCF/GNPs 膜的无试剂电化学免疫传感器讨论的开题报告摘要：无试剂电化学免疫传感器是一种高灵敏、高选择性且操作简单的生物传感技术。本讨论旨在通过基于多孔氮化硅(MHCF)和石墨烯纳米片(GNPs)的复合膜，实现对目标抗原的检测。具体而言，我们将在 MHCF表面修饰抗原特异性抗体，并通过循环伏安法和阻抗谱等电化学技术，讨论 MHCF/GNPS 膜在不同条件下的电化学性能，并探究抗原抗体相互作用对其性能的影响。讨论结果将为无试剂电化学免疫传感器的开发和应用提供理论基础和技术支持。关键词：无试剂电化学免疫传感器；多孔氮化硅；石墨烯纳米片；抗原特异性抗体；电化学性能Abstract:Reagent-free electrochemical immunosensors are a highly sensitive, selective and easy-to-operate biosensing technology. This study aims to detect the target antigen by the composite film based on macroporous hexagonal carbon ferrochrome (MHCF) and graphene nanosheets (GNPs). Specifically, we will modify antigen-specific antibodies on the surface of MHCF, and study the electrochemical properties of MHCF/GNPS film under different conditions by cyclic voltammetry and impedance spectroscopy. We will also explore the impact of antigen-antibody interactions on its performance. The results of this study will provide theoretical and technical support for the development and application of reagent-free electrochemical immunosensors.Keywords: Reagent-free electrochemical immunosensor; Macroporous hexagonal carbon ferrochrome; Graphene nanosheets; Antigen-specific antibody; Electrochemical properties
