**4. Conclusion**

A bioreceptor, a transducer, and electronic circuitry comprising an amplifier, processor, and display make up a biosensor's three primary parts. The analyte is recognized by the bioreceptor, such as enzymes or antibodies. The transducer transforms the signal from the bioreceptor into a quantifiable form. Biosensors can make use of several energy sources, including light and charge. The electrical signal is exhibited after being amplified. Biosensors are employed in a variety of industries, including biotechnology, healthcare, agriculture, and environmental investigations. Biosensors are becoming more compact, intelligent, and adaptable thanks to technological advancements. They can be used for disease detection, environmental monitoring, food safety, and medication development. Real-time monitoring and individualized healthcare are made possible by the integration of biosensors with artificial intelligence, machine learning, and the Internet of Things. However, the simplicity, affordability, sensitivity, and accuracy of biosensors still need to be improved. It is essential to develop point-of-care diagnostics and prognostics, and biosensors can completely change how medicine is practiced. Due to ongoing research, future biosensors are expected to be increasingly effective and extensively used.
