应用
- 色谱分离：硅胶广泛用作色谱固定相以分离各种化学物质。新型改性硅胶，如五溴苄基改性硅胶，可提高烟酰胺等代谢产物的分离效率。可高度精密和准确地定量生物相关分子，对药物分析和代谢组学研究有重要意义(Ozaki et al., Analytical Biochemistry, 2022)。
- 环境污染物检测：用硅胶制备的分子印迹聚合物(MIP)可选择性地识别与结合环境污染物。代表性的一个应用是在分子印迹硅胶中包埋量子点，用于检测食品样品中的氨基咪唑-氮杂脂芳烃(AIA)。该方法具有高选择性和特异性，是适合食品安全和环境监测的强大工具(Qiao et al., Current Analytical Chemistry, 2021)。
