Continuous and long-term monitoring of medicines in biological systems could offer personalized pharmacokinetic reports but is challenging due to the complexity of the biological environment in living organisms. Here, the authors present a photoelectrochemical biosensor with single atom Cu on TiO2-x as recognition unit for selective, precise, long-term tetracycline monitoring in living organisms.
