“…Gas sensing with PEDOT:PSS OECTs was performed by adjusting the polymer thickness resulting in a response to nitric oxide with a limit of detection of 350 ppb (Lin et al 2009). Similar devices were also used for in vitro cell action potential measurements (Cellot et al 2015), and for in vivo applications (Khodagholy et al 2011;Ludwig et al 2006;Williamson et al 2015).…”

“…Other electrode substrates have been used relatively little, exemplified by gold in an electrochemical quartz-crystal microbalance (ECQM) [8] or glassy carbon [9]; in addition, different assemblies containing PEDOT obtained in combination with carbon nanotubes [10] or carbon nanofibres [11] have also been reported. PEDOT has been applied to the detection of several important chemically and biologically relevant compounds such as hydrogen peroxide [12,13], nitric oxide [14], dopamine [9] and ascorbic acid [15].…”

Characterisation of the modified electrodes was done by cyclic voltammetry and electrochemical impedance spectroscopy and the stability of the polymer films was probed. The coated electrodes were tested for application as hydrogen peroxide sensors, by oxidation and reduction. A novel polymer film was also formed by modification of CFE by co-electropolymerisation of EDOT and the phenazine dye neutral red (NR) -(PEDOT/PNR) with a view to enhancing the properties for sensor applications. It was found that hydrogen peroxide reduction at the PEDOT/PNR coated electrodes could be carried out at a less negative potential, the sensor performance comparing very favourably with that of other polymer-modified electrodes reported in the literature.

“…The results show that doping Fe(salen) in PEDOT:PSS is improved the sensor response to CO. The response (T res ) and recovery (T rec ) times (defined as the time needed to reach 90% of the steady state response and recovery when gas is introduced or removed) was around 30 s for response and approximately 5 s for recovery [9]. This response time depends on the gas flow rates.…”

“…In addition, PEDOT:PSS thick films-modified electrodes have been used for sensing nitricoxide (NO) gas. Lin et al [9] showed that the PEDOT:PSS film demonstrated the highest response to NO gas at room temperature and the response increased with increasing the PEDOT:PSS film thickness from 2.3 to 5.0 mm. In 2014, Hongxia and Ruiquan [10] investigated the behavior of SmBaCuMO 5+d (M = Fe, Co, Ni) toward NH 3 gas in room temperature.…”
