Method for detecting caffeine molecules

The invention relates to a method for detecting caffeine molecules, and belongs to the technical field of photonic crystals and molecular imprinting. According to the technical scheme, the method mainly comprises the steps: preparing a caffeine molecularly imprinted polymer precursor solution, preparing a caffeine molecularly imprinted polymer membrane based on a one-dimensional photonic crystal structure, preparing a caffeine molecularly imprinted membrane, determining a linear equation, and determining the caffeine content in a sample. Compared with a traditional molecular imprinting preparation method, the preparation method provided by the invention combines the one-dimensional photonic crystal structure, and the thin film prepared by combining the molecular imprinting technology and the photonic crystal technology is simple to operate and good in repeatability in practical application. 本发明涉及一种咖啡因分子的检测方法，属于光子晶体和分子印迹技术领域。本发明的技术方案主要包括：制备咖啡因分子印迹聚合物前驱液、制备基于一维光子晶体结构咖啡因分子印迹聚合物膜、制备咖啡因分子印迹膜、确定线性方程、测定样品中咖啡因含量。本发明所
