Adsorptive mediated transcytosis (AMT) is a biological process where molecules are transported across a cell. This process involves the cell membrane adsorbing molecules, internalizing them via endocytosis, and then transporting them across the cell to be released on the other side. AMT is particularly significant in the context of nanotechnology, where it offers a pathway for delivering nanoparticles and other therapeutic agents across biological barriers such as the blood-brain barrier.
