Electrocatalytic determination of captopril in real samples using NiO nanoparticle modified (9,10-dihydro-9,10-ethanoanthracene-11,12-dicarboximido)-4-ethylbenzene-1,2-diol carbon paste electrode

- A novel nanoparticle paste electrode was used for electrooxidation of captopril.
- A simple method for synthesis on NiO nanoparticles.
- This sensor was used for the determination of captopril in patient human urine.
