Insulin sensor based on nanoparticle-decorated multiwalled carbon nanotubes modified electrodes

- GC electrodes modified with carbon nanotubes decorated with Ni(OH)2 nanoparticles.
- Electrochemical deposition of Ni(OH)2NPs from a dinuclear paddle-wheel Ni complex.
- Modified electrodes with a persistent catalytic activity towards insulin oxidation.
- Insulin determination in both, pharmaceuticals and spiked human plasma samples.
