Electrochemical biosensors allow portable applications for monitoring cancer biomarkers, which is especially relevant for screening programs targeting early detection. Yet, these devices need electrical energy and electronic parts behind the overall measuring process. This work presents a first approach to eliminate these requirements, by using a photovoltaic cell as electrical power source and an electrochromic cell as signalling element.
