Design of Embedded System for Electrochemical Immunosensor Using NI myRIO

Integrated electrochemical lateral flow immunoassays (eLFIAs): recent advances

“…Kiba et al 77 developed an electrochemical test strip based on sandwich-type immune recognition with labelled Gox. After the immune reaction is completed in the antibody capture area, a substrate containing glucose and Fe(CN) 6 3− is added to generate Fe(CN) 6 4− through a redox reaction catalysed by the GOx captured in this area. Finally, the oxidation current of the substance is detected using a Pt electrode placed 2 mm downstream.…”

“…Not only is it easy to use, portable and quick at detection, but it also has outstanding sensitivity, accuracy and selectivity compared with the traditional LFIA. Furthermore, eLFIA is easy to integrate with miniature potentiometers that are compatible with smartphones, embedded devices, portable analyzers, etc., [6][7][8] facilitating the miniaturization, automation and intelligence of the detection system. Direct conversion of biological events into electronic signals has also gradually become possible owing to the continuous innovation in bio-nano materials and modified electrodes.…”
