Receptor-Mediated Cellular Uptake of Nanoparticles: A Switchable Delivery System

Authors


Abstract

One way to eliminate cell-membrane destruction by cellular delivery of nanoparticles is the adoption of a natural pathway by encapsulating inorganic particles into protein spheres to enable potentially harmless cellular uptake by endocytosis. The bio-nanoparticles produced show good catalytic efficiency, supporting the survival of cells under oxidative stress if internalized into cells, and the receptor-mediated delivery offers the possibility of controlling cellular uptake by switching off endocytosis with appropriate inhibitors.
