Graphical Abstract

Crosslinking vesicles with magnetic nanoparticles produced MNPVs, self-assembled “nanopills” that can be “unlocked” by an alternating magnetic field (AMF), releasing chemical messengers stored within the vesicles. When MNPVs are co-immobilized with cells in a hydrogel matrix, exposure to an AMF magnetic signal releases the chemical messengers, which then induce a cellular response.
