Abstract: The invention provides a device, method, system and program for intelligent in vivo cell-level chemical or genetic material delivery; wherein multiple injectable biocompatible physical delivery device containers are used to selectively administer medicine, chemical(s) or genetic materials to a target cell in a patient, human or animal, with reduced systemic toxicity; said delivery device container includes an internal contents-to-cell transfer mechanism, usually a syringe; a biological “key” molecule, magnetic device or vibration frequency signature sensor placed on the surface of the delivery device container which is adapted to selectively bind to said target cell directly or indirectly; a “tag” placed on the surface of the delivery device container, usually metallic and biocompatible in nature, which will display to an observer when scanned through external devices such as x-ray, MRI, CT, sound, etc.
