表面增强拉曼光谱对饮料中核黄素的检测摘 要维生素涵盖各种类型的有机化合物，而这些有机化合物恰恰又是生物体当中必需的微量元素。此类元素仅能借助于饮食等外部手段获得，生物体无法自行产出。通常情况下，糖类及其脂肪将能构成细胞，并由此形成一定的能量然而维生素却并不含有此项功能。但是，生物体若想实现自身的新陈代谢，必须依赖于维生素的调节功能。自从发现表面增强拉曼光谱（SERS）直到现在，在这几十年里的高速发展，围绕 SERS 技术已经取得了许多可喜可贺的成绩。SERS 能够提供简单、快速而且更重要的是无损伤的定性定量分析。所以，本文检测饮料中的核黄素的应用基于纳米银胶的 SERS 的检测技术。关键词：维生素；表面增强拉曼光谱；纳米银胶；核黄素PAGE \* MERGEFORMATIIAbstractVitamins are the collective name for a series of organic compounds. They are the micronutrients needed by organisms, and they are generally not produced by organisms themselves and need to be obtained through diet and other means. Vitamins can not produce energy like sugars, proteins, and fats, forming cells, but they regulate the metabolism of organisms. Since the discovery of surface Enhanced Raman spectroscopy (SERS), after decades of rapid development, around the SERS Technology has achieved a lot of gratifying results. SERS can provide simple, fast and, more importantly, non-damaging qualitative and quantitative analysis, Therefore, This paper applies SERS detection technology based on nanometer silver gel to detect riboflavin of vitamin in beverage.Key words: Vitamins; surface enhanced Raman spectroscopy; nano-silver gum; RiboflavinPAGE \* MERGEFORMATII目 录1 前 言............................................................................................................................11.1 核黄素概述.........................................................................................................11.1.1 维生素简介.........................................................................
