Environmental biosensors are devices that detect and measure biological or chemical substances in the environment. They use living organisms or biological materials to identify pollutants, toxins, or other harmful agents in air, water, and soil. This technology helps monitor environmental health and safety, providing valuable data for research and regulatory purposes. These sensors can be used in various applications, such as water quality monitoring, air pollution detection, and soil analysis. By providing real-time information, environmental biosensors play a crucial role in protecting ecosystems and public health, enabling timely responses to environmental threats.
