Abstract

The establishment of (19)F NMR signal regulation and the application of this strategy to develop a multi-modal (19)F NMR probe for monitoring enzymatic activity using nanoparticles as a signal regulator is described; water-soluble perfluorinated cubic silsesquioxane was synthesized and immobilized onto the silica nanoparticles for suppressing the signals; (19)F NMR signals of the probes were recovered by releasing from nanoparticles.

摘要
