Electrochemical biosensors for enhanced detection of diabetes mellitus

The worldwide incidence of diabetes mellitus (DM), as a long-term metabolic condition, continues to rise, creating an urgent need for accurate and efficient diagnostic methods to identify and treat the disease early. Among various analytical technologies, electrochemical biosensors stand out for their exceptional attributes, including precise detection, selective response, quick results, and affordable implementation. The current review study examines the latest developments in electrochemical biosensor technology designed specifically for diabetes detection, emphasizing novel approaches in blood sugar monitoring and tracking key diabetes indicators, including HbA1c, insulin levels, and ketones. The discussion encompasses cutting-edge developments such as sensors incorporating nanomaterials, non-enzymatic detection systems, and portable monitoring devices, emphasizing how these innovations improve both technical capabilities and patient experience. This review also demonstrates how next-generation electrochemical biosensors could fundamentally change diabetes care and monitoring, leading to more widely available and accurate disease tracking methods.
