Heavy metal sensors and integration.

Heavy metal sensors and integration. Heavy metal sensors and integration plastic/paper-based electrochemical stripping sensors for heavy metals (Cd, Pb) along with the Technical record and non-expert summary. A batch of 10 printed sensors (each one containing 20 three-electrode systems: working, reference and counter electrode). The metal sensors will be applied in the robotic boats. Validation will relate to selectivity, sensitivity, limit of detection, precision and response time.
