Autonomous targeting and release of drugs at their site of action are desired features of nanomedical systems. Now, scientists have designed a nanomotor that has these functions: An antitumor drug encapsulated in self-propelled, self-assembled stomatocytes is carried across the cellular membrane and released inside the cell upon a chemical redox signal that disassembles the vesicle membrane.
