Biosensors
Biosensors are analytical devices that combine a biological recognition element (e.g., enzymes, antibodies, cells) with a physicochemical transducer to detect and quantify specific biological or chemical substances. They convert biological responses into measurable electrical, optical, or other signals, enabling real-time monitoring in fields like healthcare, environmental science, and food safety. Common examples include glucose monitors for diabetes management and DNA sensors for genetic analysis.
Developers should learn about biosensors when working on applications in biotechnology, medical devices, or IoT health monitoring, as they enable integration of biological data into digital systems. This is crucial for developing wearable health trackers, point-of-care diagnostic tools, or environmental sensors that require real-time biological feedback. Understanding biosensors helps in designing software for data acquisition, signal processing, and user interfaces in these domains.
