Techniques for atomic force microscope manipulation of living cells include functionalizing a nanoscale tip of a microscale cantilever with a first ligand for a first receptor associated with a surface of a first type of cell. The method further comprises, controlling the cantilever to cause the first ligand on the nanoscale tip to contact the first receptor on a surface of a living cell of the first type in a particular temporal pattern to induce a target response by the living cell. Other techniques for controlling an atomic force microscope comprising a nanoscale tip include controlling the cantilever to cause the nanoscale tip to contact a living cardiomyocyte at a predetermined pressure. The cantilever is also controlled to turn off vertical deflection feedback after contacting the cardiomyocyte and collecting deflection data that indicates a time series of nanoscale vertical deflections of the microscale cantilever caused by the living cardiomyocyte.
