In recent years, Near Field Communication (NFC) technology has become widespread in the field of electrochemical sensors, enhancing their functionality and ease of use since enables wireless communication and data transfer at close proximity, simplifying sensor setup, calibration, and data retrieval . This technology allows seamless data exchange between sensors and mobile devices, providing users with an effective way to collect and analyze electrochemical data in real-time. Herein, we present a smartphone-controlled NFC potentiostat integrated with a flow-through electrochemical microfluidic device via wireless communication, and with the data-display conversion on Android smartphones ( Fig. ). We also compared this configuration with the performance offered by a standard potentiostat ( PalmSens4) and by conventional ELISA for the evaluation CRP levels in artificial serum, plasma, and whole blood.
