Electrochemical biosensors face challenges related to sensitivity, specificity, and reliability. Future directions involve advancing materials science, incorporating artificial intelligence for data analysis, and developing more robust and miniaturized devices for implantable biosensors [3,4].

The transducer converts the biochemical signal generated by the recognition event (binding of the target biomolecule) into an electrical signal. Common transducers include potentiostats and amperostats. Recognition element is a crucial component specific to the target biomolecule. It can be an enzyme, antibody, DNA probe, or aptamer. The recognition element selectively binds to the target analyte, triggering an electrochemical response. This is a crucial component specific to the target biomolecule.

Signal Amplification to enhance sensitivity, signal amplification techniques, such as enzyme amplification or nanomaterial modification, are often employed. Electrochemical biosensors typically use three primary detection methods: amperometry (measuring current), potentiometry (measuring voltage) and impedance spectroscopy (measuring changes in impedance) [5].
