A wirelessly controlled implant, which delivers precise drug doses into the patient’s body, has had a successful first clinical trial, bringing the possibility of the “pharmacy on a chip” that could transform drug delivery closer.
Unlike most drug delivery devices, which release medicine gradually, the new microchip releases doses at specified times. These can be preprogrammed into the device or triggered by a doctor using the wireless communications facility.
To make the technology even more useful, the MIT researchers plan to combine it with sensors that can detect biochemical changes in patients’ bodies, which could indicate how well the treatment is working and how much drug is needed.
