我们提出了一些剥离的钛基金属有机框架（mof）纳米片作为具有超高电离效率、自由基质背景、显著分散性和耐酸性的基质。结合mof和二维纳米材料的特点，NTU-9纳米片基质也表现出合适的带隙能量和优越的光吸收性能，远远优于其他代表性的mof。以NTU-9纳米片为基质，在正离子和负离子反射模式下分析了涉及低质量区域的大范围小分子。超高效的NTU-9纳米片基质成功应用于血清中葡萄糖的定量测定，作为糖尿病的临床诊断指标。(C) 2018 Elsevier B.V.版权所有
We proposed some exfoliated Ti-based metal-organic frameworks (MOFs) nanosheets as matrices with ultrahigh ionization efficiency, free matrix background, significant dispersibility and acidic resistance. Combining the features between MOFs and 2-D nanomaterials, the NTU-9 nanosheets matrix also demonstrated suitable band gap energy and superior photoabsorption properties, much better than other representative MOFs. A wide range of small molecules that involving low mass region were also analyzed with NTU-9 nanosheets as the matrices in both positive-ion and negative-ion reflector modes. The ultra-efficient NTU-9 nanosheets matrix was successfully applied to serum for quantitative determination of glucose as a clinical diagnosis indicator of diabetes mellitus. (C) 2018 Elsevier B.V.
