Keywords: cell receptors; drug targeting; endocytosis; nanoparticle corona; nanoparticle uptake; Introduction Nano-sized materials are widely studied in nanomedicine for their potential use as drug carriers, in imaging, and for diagnostic purposes [1][2][3]. Because of their size, they can interact with

These natural nano-sized objects are usually recognized by specific cell receptors at the plasma membrane and they are internalized by cells using the cell endocytic machinery [4]. Similarly

The aptamer that specifically binds to a certain protein is usually selected by the technique named
