Figure 3. Representative examples of enhanced nanoparticle targeting to EGF receptors using nanoparticle decoration with anti-EGF receptor antibody fragments.
(A) Cell viability assay shows a significant decrease in cell viability following treatment with varying DDP concentrations delivered via anti-EGF receptor fragment-labeled nanoparticles, compared with nontargeted nanoparticles or free drug. (Bi) Anti-EGF receptor fragment-labeled red fluorescent polymeric micelles undergo higher internalization compared with (Bii) the nontargeted formulation.
