Abstract

The invention discloses an organic compound-derived magnetic carbon nanomaterial with a metallic framework and application of the organic compound-derived magnetic carbon nanomaterial, and belongs to the technical field of organic nanomaterials. The organic compound-derived magnetic carbon nanomaterial is prepared by the following steps: with cobalt (II) and ferrum (III) as central ions, 2-methylimidazole, terephthalic acid and 4,4'-diphenic acid as ligands, and polyvinylpyrrolidone as dispersing agents, forming a cobalt-based and ferrum-based metallic framework organic compound in a self-assembly manner at room temperature; and with the cobalt-based and ferrum-based metallic framework organic compound as a template, carrying out high-temperature calcining under nitrogen protection, so as to obtain the magnetic carbon nanomaterial. The organic compound-derived magnetic carbon nanomaterial is applied to a separation carrier of N-glycoprotein; through the interaction between a large number of carbon and glycosyl of a nano-scale magnetic carbon material, appropriate mesopores and high specific surface, a novel method for simply and rapidly extracting the N-glycoprotein from a biological sample is built; and by combination with a biological mass spectrometry detection method, the condition that the synthetic magnetic carbon nanomaterial has high repeatability, significant specificity, high enrichment factor and low detection limit on the N-glycoprotein is proved.

Description

technical field [0001] The invention belongs to the technical field of organic nanometer materials. Background technique [0002] Metal-organic frameworks (MOFs) are a new type of material, which are usually hybridized by metal ions and oxygen-containing, nitrogen-containing multi-dentate organic ligands through a self-assembly process, and have a three-dimensional periodic network structure of regular nanopores. Compared with other porous materials, MOFs materials have large specific surface area, high porosity, regular and adjustable pore structure, and easy-to-functional framework metal ions and organic ligands, so they are widely used in catalysis research, gas adsorption, biomedicine , Magnetic functions and other fields have potential application value. [0003] Protein glycosylation is one of the most important and common post-translational modifications of proteins. Glycosylation participates in various biological processes by changing various biological properties...
