Figure Lengend Snippet: ( A ) Scheme of nanoparticle diffusion in 3D SKOV-3 cells (ovarian cancer cell line) embedded in Matrigel ® that shows impeded access of nanoparticles to the SKOV-3 cancer cells due to the Matrigel ® presence. ( B ) Confocal images of SKOV-3 cells and nanoparticles in the Matrigel ® . ( C ) Quantification of nanoparticle diffusion distance and the related percentage of SKOV-3 cells accessed by the nanoparticles. The diffusion distance was indicated as 50% of the initial nanoparticle concentration away from the reservoir (orange line). The corresponding distance also reflected the percentage of cells the nanoparticles had access to (orange line).
