“…47,48 But the interaction of neutral molecules, such as alcohols is much less pronounced. 47 Because the dominating mechanism in detecting alcohols is swelling, 49 the responding time for conducting polymer sensors (typically ∼14 min 49 ) is significantly longer than our polymer−metal hybrid sensor (∼100s). In addition, due to the swelling mechanism, the selectivity among organic solvent vapors is not ideal.…”

We report a novel room temperature methanol sensor comprised of gold nanoparticles covalently attached to the surface of conducting copolymer films. The copolymer films are synthesized by oxidative chemical vapor deposition (oCVD), allowing substrate-independent deposition, good polymer conductivity and stability. Two different oCVD copolymers are examined: poly(3,4-ethylenedioxythiophene-co-thiophene-3-aceticacid)[poly(EDOT-co-TAA)] and poly(3,4-ehylenedioxythiophene-co-thiophene-3-ethanol)[poly(EDOT-co-3-TE)]. Covalent attachment of gold nanoparticles to the functional groups of the oCVD films results in a hybrid system with efficient sensing response to methanol. The response of the poly(EDOT-co-TAA)/Au devices is found to be superior to that of the other copolymer, confirming the importance of the linker molecules (4-aminothiophenol) in the sensing behavior. Selectivity of the sensor to methanol over n-pentane, acetone, and toluene is demonstrated. Direct fabrication on a printed circuit board (PCB) is achieved, resulting in an improved electrical contact of the organic resistor to the metal circuitry and thus enhanced sensing properties. The simplicity and low fabrication cost of the resistive element, mild working temperature, together with its compatibility with PCB substrates pave the way for its straightforward integration into electronic devices, such as wireless sensor networks.

“…Recently, for non‐enzymatic glucose detection, transition metals, metal oxides, carbon nanomaterials, or conducting polymers have been used as electrode material. Conducting polymers have found wide application in smart materials [7–12], sensors [13–18], and biomaterials [19,20] in recent years due to their superior electrical properties. Besides, conducting polymer provides a large surface area for the immobilization of metal nanoparticles because of its electrodeposits homogeneously, strongly adheres to the surface, and has chemical stability.…”

In this work, rapid, sensitive, practical, and economical strategy for non‐enzymatic glucose sensor has been reported based on a modification of copper nanoparticles upon conducting polymer with high surface area (Cu@PCR). Firstly, PCR conducting polymer electrode (PCR) has been successfully fabricated by electrochemical polymerization of a specially synthesized and characterized star‐shaped carbazole derivative. Then copper nanoparticles have been successfully electrodeposited on the PCR as a practical method with cyclic voltammetry. The morphologies of the synthesized materials have been characterized by scanning electron microscopy (SEM) and energy‐dispersive spectroscopy (EDS) measurements. The Cu@PCR sensor platform has been displayed a synergistic effect of high catalytical properties of copper nanoparticles and high electroactive properties of PCR towards the glucose oxidation in alkaline medium. The Cu@PCR sensor platform has shown high sensitivity of 847 μAmM−1cm−2, good stability (10 weeks), a low detection limit of 0.043 μM, and a fast response of 3 s for the non‐enzymatic electrochemical detection of glucose. This organic−inorganic hybrid composite sensor is a promising candidate for the fabrication of a highly sensitive and rapid glucose‐sensing with the simple preparation procedure and use of a low‐cost precursor.
