Description
Technical Field
The invention relates to the technical field of amino acid detection, in particular to a MOF-Cd probe for detecting lysine and a preparation method and application thereof.
Background
Amino acids are indispensable components in organisms, and the growth and development processes of the organisms cannot be separated from the amino acids. In the aspect of detecting certain diseases, the content of the amino acid can be directly detected. For example, histidine (His), in addition to being an essential amino acid for human growth, is a regulator of neurotransmitter and metal transmission in mammals. Asthma and late cirrhosis can lead to abnormal levels of histidine-rich proteins; aspartic acid (Asp) is an endogenous amino acid for human growth, and a certain amount of aspartic acid in cells is essential for the cell proliferation process and respiration. Thus, detection of abnormal levels of aspartate can be used as an early diagnosis of tumors.
Conventional methods for detecting amino acids include: the methods of spectral analysis, high performance liquid chromatography, electrochemistry and the like have the defects of high cost, long time, complex test and the like. In recent years, researchers have begun investigating the specific detection of amino acids using MOFs as fluorescent probes. Lee scientific research group reports that a fluorescent metal organic framework (LMOF) based on copper iodide (I) clusters, the selectivity of the LMOF dispersed in water to Cys exceeds that of other amino acids, and K is calculated SV Has a value of 6.128 × 10 2 M -1 (R = 0.9914)(ji Lee, Huiyeong Ju, Jong Hwa Jung, Mari Ikeda, Yoichi Habata, and Shim Sung Lee, Conventional and mechanochemical syntheses of copper(I) iodide luminescent MOF with bis(amidoquinoline) and Its application for the detection of amino acid in aqueous solution [J]Inorg. Chem., 2019, 58, 1177-1183). Although excellent in selectivity, the recognition process is based on fluorescence quenching, and the appearance of a bright signal in a completely dark environment is more easily detected than the decrease in a completely bright signal, so that it is important to develop a fluorescent probe for detecting an amino acid based on fluorescence enhancement.
