Scientists in Switzerland have developed a tiny electronic implant that has been hailed as an important step towards personalising medicine.
Once implanted just below the skin, the chip can detect and monitor levels of different proteins and acids, and can be used to administer medications on a regular basis.
The idea is to give patients the right drugs, at the right time, to make their treatment more effective.
