    Framework of sequential biological barriers to nanoparticle drug delivery. Upon intravenous administration, drug-containing nanoparticles encounter a number of sequential obstacles hindering efficacious, site-specific delivery to tumors. Nanoparticles undergo opsonization and subsequent uptake by resident macrophages of the MPS.Author: Elvin Blanco, Haifa Shen, Haifa Shen, Mauro Ferrari, Mauro Ferrari
