Description: A creatinine biosensor is a device that measures the levels of creatinine in the blood, a chemical compound that is naturally produced in the body from the metabolism of creatine, a substance found in muscles. This type of biosensor uses electrochemical technologies to detect and quantify creatinine, providing rapid and accurate results. Measuring creatinine is crucial for assessing kidney function, as elevated levels may indicate kidney problems. Creatinine biosensors are compact, portable, and can be integrated into health monitoring systems, making them valuable tools in personalized medicine and healthcare. Their ability to provide real-time results allows healthcare professionals to make informed decisions about treatment and management of kidney diseases, as well as to continuously monitor patient health. Furthermore, their integration with IoT (Internet of Things) technologies enables data transmission to cloud platforms, facilitating health information analysis and management.
