From: Cell membrane protein functionalization of nanoparticles as a new tumor-targeting strategy
Schematic illustration of an empty biomimetic nanoparticle (NP) developed from the membrane sourced of different cells: platelets, red blood, mesenchymal, tumor and immune cells. Thanks to the cells of origin, NPs are endowed with specific features (in bold) that mediate their ability to escape the immune system, extravasate blood vessels and target tumor site.
