Assembly of different metal-organic frameworks (MOFs) into hybrid MOF-on-MOF heterostructures has been established as a promising approach to develop synergistic performances for variety applications. Here, we explore the performance heterostructure by epitaxial growth MIL-88B(Fe) onto UiO-66(Zr)-NH2 nanoparticles.

Nanometric biocompatible Metal-Organic Frameworks (nanoMOFs) are promising candidates for drug delivery. Up to now, most studies have targeted the intravenous route, related pain and severe complications; whereas nanoMOFs oral administration, a commonly used non-invasive simpler remains however unexplored.

Abstract The formation of a metal–organic framework (MOF) with nodes that have single‐molecule magnet (SMM) behaviour has been achieved by using mononuclear lanthanoid analogues, also known as single‐ion magnets (SIMs), which enormously simplifies the challenging issue making SMM‐MOFs.
