| titleOfInvention | A magnetic particle modified in situ by silver nanoparticles and its application in the separation and enrichment of β-blockers |
| abstract | The invention discloses a magnetic particle modified by silver nanoparticles in situ and its application in separating and enriching beta-receptor blockers. A preparation method of silver nanoparticle in-situ modified magnetic particles, comprising the steps of: preparing COOH-MNPs magnetic particles by a solvothermal method, and then reacting the COOH-MNPs magnetic particles with a dopa solution to obtain polyDOPA-MNPs modified with polydopa Finally, Ag nanoparticles were in situ modified on the surface of polyDOPA-MNPs magnetic particles to prepare polyDOPA@Ag-MNPs magnetic particles. The in-situ modified magnetic particles of silver nanoparticles (polyDOPA@Ag-MNPs magnetic particles) prepared by the invention can well adsorb and elute β-receptor blockers, and use ESI-MS technology to eluate the eluted magnetic particles. The supernatant was used for detection, which greatly improved the detection sensitivity. |
