Schematics for the fabrication process of guest molecules encapsulated within the ferritin cavity by different mechanisms: (A) self-assembly of ferritin controlled by different chemicals; (B) regulation of ferritin self-assembly by physical methods or genetic modification under relatively mild conditions; (C) expansion of ferritin channels by different methods. ACP, atmospheric cold plasma; PEF, pulsed electric field; MTS, manothermosonication; EP, extension peptide; HHP, high hydrostatic pressure.
