Alkyne- and azide-functionalized iron oxide nanoparticles are co-assembled at the water–oil interface and covalently linked using click chemistry under ambient conditions to create magnetic colloidosomes (see image). These colloidosomes possess high stability, size-selective permeability, and are responsive toward external magnetic stimuli.
