“…However, the major problem while fabricating enzyme-based biosensor is the immobilization of enzymes onto electrode matrix. Most of the time fabrication fails due to lose binding, chemical modification, denaturation, and loss of enzyme activity apart from instability of matrix [3]. These failures can be minimized or avoided through the proper deposition of conducting polymer matrix and also by adopting proper enzyme immobilization techniques.…”

“…The electrode configuration of the sensor varies according to the sensing mechanism. Potentiometry and amperometry are used for detection of analytes in liquids, in particular to develop polymer-based pH sensors [6][7][8][9][10] and polymer-based biosensors [11][12][13][14][15]. Alternatively, conductimetry is the most generally used technique for gas detection.…”

Electrochemically deposited polymers, also called "synthetic metals", have emerged as potential candidates for chemical sensing due to their interesting and tunable chemical, electrical, and structural properties. In particular, most of these polymers (including polypyrrole, polyaniline, polythiophene) and their derivatives can be used as the sensitive layer of conductimetric gas sensors because of their conducting properties. An important advantage of polymer-based gas sensors is their efficiency at room temperature. This characteristic is interesting since most of the commercially-available sensors, usually based on metal oxides, work at high temperatures (300-400 °C). Consequently, polymer-based gas sensors are playing a growing role in the improvement of public health and environment control because they can lead to gas sensors operating with rapid detection, high sensitivity, small size, and specificity in atmospheric conditions. In this review, the recent advances in electrodeposited polymer-based gas sensors are summarized and discussed. It is shown that the sensing characteristics of electrodeposited polymers can be improved by chemical functionalization, nanostructuration, or mixing with other functional materials to form composites or hybrid materials.

“…Finally, it is important to acknowledge some issues that may arise with CPs, such as concerns over thermal and chemical stability, the mechanical ruggedness, and tolerance to high-field electric fields of CPs (73,142), all of which may affect the performance of CP-based sensors. Recent research has focused on finding solutions to some of these issues, and the electrochemical growth of CPs in new media like ILs, as highlighted previously, has offered some improvements.…”
