“…S2 C). 26 In order to extend the applications of polyaniline as an electrochromic material for using in biosensing platform, the electrochromic feature of PANI was evaluated in phosphate buffer saline (PBS, 0.1 M, pH = 7.4) as a biological electrolyte. 27 Being electrochromic properties pH and saline dependent, it is no surprise that the PANI behavior in PBS differs from the one in 0.5 M H2SO4.…”

Finding fast and reliable ways to detect pathogenic bacteria is crucial for addressing serious public health issues in clinical, environmental and food settings. Here, we present a novel assay based on the conversion of an electrochemical signal into a more convenient optical read out for the visual detection of E. coli. Electropolymerizing polyaniline (PANI) on indium tin oxide screen printed electrode (ITO SPE), we achieved not only the desired electrochromic behavior, but also a convenient way to modify the electrode surface with antibodies (taking advantage of the many amine groups of PANI). Applying a constant potential to the PANI-modified ITO SPE induces a change in their oxidation state, which in turn generates a colour change on the electrode surface. The presence of E. Coli on the electrode surface increases the resistance in the circuit affecting the PANI oxidation states, producing a different electrochromic response. Using this electrochromic sensor, we could measure concentrations of E. Coli spanning four orders of magnitude with a limit of detection of 10 2 CFU mL -1 . In this work we show that merging the sensitivity of electrochemistry with the user-friendliness of an optical read out can generate a new and powerful class of biosensors, with potentially unlimited applications in a variety of fields.

“…Polyaniline (PAni) is one of the conductive polymers that has received much attention in its full application due to its easy synthesis route, low cost, stability in the atmospheric environment, excellent electrochemical properties, versatility, interchangeable oxidation states, and reversibility in terms of characteristics doping/dedoping acid or base. These polymers having electrical properties have aroused great interest since the 1980s, and during that time, many reports about their applications have been extensively investigated including as electronic devices [2], batteries [3], solar cells [4], sensors and actuators [5], membranes [6], anticorrosion coatings [7], and light emitting diode (LED) [8]. For batteries, PAni was widely used as anode or cathode composite material to improve conductive and catalytic properties.…”

“…The EB form is the most stable of these polymers. This condition is the most studied because the EB form could show a high conductivity level when treatment with acid given emeraldine salt (ES) form [5,[7][8][9]. Meanwhile, the application of polyaniline depends on the morphology, polyaniline oxidation state, surface properties, thermal stability, and preparation process.…”

Here, we report the effect of various drying temperature of Polyaniline (PAni) on battery PAni|Zn performance. PAni was synthesized using the electrodeposition method on the surface of the graphite sheets (GS), at 0.7 V relative to the saturated Ag/AgCl. PAni is dried with various temperature, 25, 80, 120, and 180 o C, respectively. PAni was characterized by Raman spectroscopy; then the performance Pani battery was studied in a rechargeable battery system. The measurement results found the PAni|Zn battery with 25 o C temperature drying of PAni was a good performance which the capacity density stable at 175-105 mAh g-1 until 100 cycles. Raman study showed that high-temperature drying resulted in a cleavage peak at 1188 cm-1 and increased peak intensity at 1495 cm-1. This vibrational mode appears as a stretching ν(C-C) on the semi quinonoid ring and ν(C=N) on the quinoid ring. This phenomenon indicated the changing structure of PAni to be Emeraldine base form.

“…Moreover, organic polymer with conductive properties also attracts attention. Complement to these physical properties, the organic conductive polymer also gain attention for certain purposes, such as for solar cell [1], light emitting diode [2,3], conductive ink, sensor [4][5][6][7], semiconductor [8], super-capacitor [9], energy storage [10], catalysis and catalyst supporting material [11][12][13]. In our ongoing research finding non-metallic material catalyst for alpha-pinene oxidation [14][15][16] into more valuable chemicals, it turned up on polyaniline nanoparticle (PANI-NP) as prospectus catalyst.…”

Polyaniline (PANI) is a conductive polymer and potential for application in the electronic device manufacturing. This paper discloses a recent strategy in synthesis polyaniline nanoparticle (NP-PANI) using inverse micelle (IM) microemulsion method, and also characterization of the provided products. The synthesis step was conducted by mixing of aniline as a polymer precursor with PEG 400, n-hexane, n-butanol, ammonium persulfate and hydrochloric acid in three different reaction times, i.e. for 2, 6, and 12 hours at 26 o C. NP-PANI was afforded as a brown powder in 2.87%, 1.97% and 2.30% yield for NP-PANI-IM-2, NP-PANI-IM-6 and NP-PANI-IM-12. The characteristic on ultra violetvisible and infrared spectra exhibited NP-PANI was formed as an emeraldine salt oligomer. Moreover, their morphology was observed through scanning electron microscopy (SEM) and showed a different range of nanoparticle size, i.e. 50-62, 68-72 and 58-62 nm for NP-PANI-IM-2, NP-PANI-IM-6 and NP-PANI-IM-12, respectively. These products open the potency application in material science.
