Description: A mineral biosensor is a device that measures the concentration of minerals in a sample, using biological principles to detect and quantify the presence of these elements. These biosensors combine biological components, such as enzymes or antibodies, with a transducer that converts the biological signal into an electrical or digital signal. Their design allows for high sensitivity and specificity, making them ideal for applications in a range of fields including agriculture, health, and the environment. The ability of these sensors to provide real-time results and their integration with IoT (Internet of Things) technologies makes them valuable tools for continuous monitoring of minerals in various matrices, such as soils, waters, and foods. Additionally, their portability and ease of use allow them to be utilized both in laboratories and in the field, facilitating informed and rapid decision-making. In a world where the quality of natural resources is crucial, mineral biosensors represent a significant innovation in how these essential elements are managed and controlled.
