Herein, we demonstrate a one-step, scalable, solution-processed method for the growth of nickel sulfide (NiS) nanostructures using single-source precursors (SSPs) on flexible substrate as versatile framework simultaneous detection four DNA nucleobases. The as-grown NiS exhibit broad bandgap range and spherical morphology with high surface area significant porosity, confirmed by SEM, TEM, BET analysis. Consequently, NiS/Ni-foam electrode exhibited remarkable electrochemical performance toward oxidation A, G, T, C due to its large area, activity, efficient electron transfer capacity. Under optimum conditions, demonstrated selective all nucleobases over wide linear from 200 1000 μM A 50 500 T C, low limit 159 147.6 16.8 45.9 along sensitivity 1.2 × 10-4 M-1 6.1 10-3 3.0 C. as-fabricated revealed excellent reproducibility stability nucleobase reliable DPV response under different bending twisting conditions. For immediate practical application, was utilized quantify concentration in calf thymus Escherichia coli (E. coli) DNA, resulting (G + C)/(A T) ratio 0.79 1.10, respectively. This simple, cost-effective, paves way development non-invasive, wearable biosensors potential applications early disease detection.

This study presents the electrochemical sensing of dopamine (DA) using an electrode polypyrrole/poly(3,4-ethylenedioxythiophene) (PEDOT-PPy) thin film. Electrochemical analyses PEDOT-PPy film for DA were conducted through cyclic voltammetry (CV) and differential pulse (DPV). The CV analysis demonstrated that exhibited superior activity towards due to its enhanced conductivity as a high-conducting polymer composite. DPV results indicated linear concentration level 5 nM 200 µM with minimal limit material. fabricated sensor explored sensitivity 7.27 µA/µM cm2 at 1000 diffusion coefficient 1.3 × 10–8 cm2/s. Additionally, material displayed excellent reproducibility, selectivity, stability. Therefore, composite shows potential outperforming other materials in detecting DA.
