Fig. 4From: Targeting Endothelial Cells with Multifunctional GaN/Fe NanoparticlesGuiding of nanoparticle-laden endothelial cells using a magnetic field. The control group shows the spatial distribution of a endothelial cells targeted with nanoparticles and incubated in the absence of magnetic field and b nanoparticle-free endothelial cells incubated in magnetic field. c, d The distribution of endothelial cells targeted with nanoparticles after 1 day of incubation in a magnetic fieldBack to article page
