混合式-金属有机骨架在疾病呼出气检测中的固相微萃取应用

混合式-金属有机骨架在疾病呼出气检测中的固相微萃取应用摘要：

本文研究了一种新型的混合式-金属有机骨架（co-MOF）及其在疾病呼出气检测中的固相微萃取应用。通过改变MOF中的金属离子种类，不同的有机配体和混合比例，得到一系列具有不同表面性质和孔径结构的co-MOF材料。同时，这些材料在空气和依甲烷等模拟物质中的吸附行为也进行了研究。结果表明，当co-MOF材料表面上的金属离子种类为Zr和有机配体为BDC时，其具有良好的吸附性能和较大的比表面积，对于疾病呼出气中的挥发性有机化合物（VOCs）具有高效、选择性和灵敏度的吸附能力。最后，将这种co-MOF材料应用于呼出气中VOCs的固相微萃取提取与检测，取得了较好的分离富集效果，并成功地应用于实际的疾病诊断中。
