Interfacial Amine Engineering Unlocks Enhanced MRI Relaxivity in Silica-Coated Hematite Nanoparticles.
Engineering the surface architecture of MRI contrast agents is fundamental to achieving superior contrast efficiency and multifunctional therapeutic capability. We report the silica-coated hematite (SIO) functionalized with amine groups via (3-aminopropyl) trimethoxysilane (APTMS) to assess their effects on MRI relaxiv...
