摘要：An available pathway to prepare the ionized covalent organic nanosheets (iCONs) has been proposed by a metal-assisted aqueous-phase exfoliation route from covalent organic frameworks. The soluble and belt-shaped iCONs could immobilize a large quantity of proteins (2.73 mg/mg, BSA/iCONs) and hence serve as transporters to enhance the protein uptake by cancer cells. Meanwhile, their energy-dependent endocytosis pathway via clathrin-coated pits has been proved as well.
