The unique combination of DNA bases is essential for storing genetic information. A reliable and accurate electrochemical sensor based on a gold/palladium–polypyrrole/graphene nanocomposite (Au/Pd–PPy/GR) has been prepared to individually and simultaneously detect guanine (G), adenine (A), thymine (T), and cytosine (C). The bimetallic nanomaterial (Au/Pd–PPy) is used to enhance the sensing performance of DNA bases, and the GR could further increase the electroactive area and amplify the electrochemical response. As expected, the electrochemical sensor shows excellent electrocatalytic activity with well-separated current responses at 0.704 V (G), 0.976 (A), 1.164 (T), and 1.348 V (C). The prepared sensor exhibits the linear range of 1–350 μM for G, 5–300 μM for A, 20–900 μM for T, and 10–700 μM for C. The developed device is also demonstrated as an excellently sensitive and highly selective sensor to identify the four bases in calf thymus DNA, which provides the application of electrochemical sensors in bioscience.

The combined features of functional electronic devices have attracted significant attention because of high demand for promising energy technologies. Of particular interest are electrochromic (EC) supercapacitors, which can visually display the level of stored energy in real-time. Here, we demonstrate the EC energy storage properties of pure and doped Prussian blue (PB) thin films fabricated using electrodeposition. The pure PB films produced various colours at different potentials during their charging-discharging cycles, but they suffered from instability. To overcome this, we doped PB films with ruthenium (Ru), iridium (Ir), and molybdenum (Mo). Of the doped specimens, the Mo-doped PB films exhibited the most promising EC energy storage properties, with a specific capacity of 399.7 F g À1 at 1 A g À1 , a colouration efficiency of 110.2 cm 2 C À1 , and an excellent optical density difference of 0.92. The Modoped PB films also demonstrated ultra-fast colouration and bleaching behaviour within 3.25 and 4.04 seconds, respectively. Our experimental findings suggest that Metal-doped PB films can be employed for practical application.
