Publication highlighting challenges in nanoparticle-based drug delivery from Iversen and coworkers
In a recent article in Journal of Nanobiotechnology, Tore-Geir Iversen and coworkers show that quantum dots covered with ricin B is taken up by a macropinocytosis-like mechanism. The results demonstrate that the internalization of a ligand-nanoparticle conjugate can be dependent on other endocytic mechanisms than those used by the free ligand. The results are thus highlighting the challenges of using ligand-mediated targeting of nanoparticle-based drug delivery vehicles to cells of diseased tissues.”
