1. A composition, comprising:
branched nanoparticles comprising a metal-organic framework, the metal-organic framework comprising a metal ion and a multidentate ligand,
wherein the branched nanoparticles have a hydrodynamic diameter of less than or equal to 2 μm when measured by dynamic light scattering in methanol, an aspect ratio of at least 5, and branches having a largest diameter of less than or equal to 200 nm; and
wherein the metal-organic framework is HKUST-1 or a zeolitic imidazolate framework.
