 Electrochemical creatinine sensors are revolutionizing the field of point-of-care diagnosis by providing accurate and reliable measurements of creatinine levels in patients. Enzyme-based and enzymeless electrochemical sensors offer distinct advantages over traditional methods, including high sensitivity, low cost, and ease of use. Despite these benefits, further research is needed to improve the accuracy and reliability of these devices, particularly when it comes to detecting creatinine levels in elderly and at-risk populations.
