Abstract
A sensor for the simple and sensitive measurement of hydrogen peroxide has been developed which is based on screen printed electrodes (SPEs) modified with Prussian blue nanoparticles (PBNPs) deposited using piezoelectric inkjet printing. PBNP-modified SPEs were characterized using physical and electrochemical techniques to optimize the PBNP layer thickness and electroanalytical conditions for optimum measurement of hydrogen peroxide. Sensor optimization resultedin a limit of detection of 2 × 10-7 M, a linear range from 0 to 4.5 mM and a sensitivity of 762 μA·mM-1 ·cm-2 which was achieved using 20 layers of printed PBNPs. Sensors also demonstratedexcellent reproducibility (
