US scientists say they have taken a step towards microchips being implanted under a patient's skin to control the release of drugs.
The futuristic idea that microchips could be implanted under a patient's skin to control the release of drugs has taken another step forward.
US scientists have been testing just such a device on women with the bone-wasting disease osteoporosis.
The chip was inserted in their waist and activated by remote control.
A clinical trial, reported in Science Translational Medicine, showed the chip could administer the correct doses and that there were no side effects.
