Experimental results for enhanced permeability of vascular endothelium by an external magnetic field. (a) Schematic diagram of magnetic particle containing a magnetite nanocrystal and a phospholipid-polyethylene glycol (PEG) coating. (b) Endothelial cells containing magnetic particles incubated without and with magnetic field. (c) Particles with magnetism were injected into a mouse lateral tail vein, and the opposite lateral tail vein was placed under the external magnetic field. (d) Magnetic particles in the mouse tails quantified by a superconducting quantum interference device. (Reproduced with permission from Qiu et al. [133] (Copyright 2017 Nature Publishing Group)).
