| 英文摘要 | in this work, a novel core-shell structured gold@graphitized mesoporous silica nanocomposite (au@gmsn) was synthesized by in situ graphitization of template within the mesochannels of mesoporous silica shell on gold core and demonstrated to be promising nanomaterials for surface-assisted laser desorption/ionization time-of-flight mass spectroscopy (saldi-tof ms). the integration of the graphitized mesoporous silica with the gold nanoparticles endowed au@gmsn with large surface areas of graphitic structure, good dispersibility, and strong ultraviolet (uv) absorption. au@gmsn exerted the synergistic effect on the efficient detection of small-molecular-weight analytes including amino acids, neutral saccharides, peptides, and traditional chinese medicine. the au@gmsn-assisted laser desorption/ionization exhibited the following superiorities: high ionization efficiency, low fragmentation interference, favorable salt tolerance, and good reproducibility. moreover, because of the large hydrophobic inner surface area of the graphitized mesoporous silica shell, the au@gmsn demonstrated its promising capacity in the pre-enrichment of aromatic analytes prior to saldi-tof ms, which favored rapid and sensitive detection. |
