Inherent anchorages in UiO-66 nanoparticles for efficient capture of alendronate and its mediated release

Abstract

Zr-based MOF nanoparticles were applied as efficient carriers for alendronate delivery, and an unprecedented drug loading capacity was achieved thanks to the inherent drug anchorages of Zr-O clusters therein. The encapsulated drug featured with a pH-dependent release profile, and inhibited the growth of cancer cells more efficiently than the free drug.
