Design of perfluorohexane (PFH)-loaded magnetic hollow iron oxide nanoparticles (HIONs) for magnetic droplet vaporization (MDV)-based intelligent stimuli-responsive cancer theranostics. (a) Schematic illustration of the MDV process mediated by PFH-HIONs, including encapsulation of PFH into HIONs and subsequent vaporization of PFH induced by the a.c. magnetic field. (b) The scheme of the MDV apparatus for MDV process to generate microbubbles. (c) In vivo MDV process for imaging-guided cancer theranostics.
