Description: Heavy metal biosensors are innovative devices designed to detect the presence of toxic metals in the environment, such as lead, mercury, and cadmium. These sensors combine biological elements, such as enzymes or antibodies, with electrochemical components to provide a rapid and accurate response to contamination. Their operation is based on the interaction between the heavy metal and the biological component, generating a signal that can be measured and analyzed. The importance of these biosensors lies in their ability to monitor the quality of water, soil, and food, thus contributing to the protection of public health and the environment. Furthermore, their integration into Internet of Things (IoT) systems allows for real-time data collection, facilitating informed decision-making regarding resource management and environmental risk prevention. In a world where heavy metal pollution is a growing concern, biosensors represent an essential tool for environmental monitoring and sustainability.
