Abstract

Abstract: A comparison of the analytical performances of four different (bio)sensor designs in H2 O2 determination is discussed. The (bio)sensor designs developed were based on the use of (i) multiwalled carbon nanotubes (MWCNT), zinc oxide nanoparticles (ZnONP), prussian blue (PB); (ii) MWCNT, ZnONP, PB and ionic liquid (IL); (iii) MWCNT, ZnONP and horseradish peroxidase (HRP) and (iv) MWCNT, ZnONP, HRP and IL modified glassy carbon electrode (GCE). A performance comparison of (bio)sensors showed that the one based on HRP/IL‐MWCNT‐ZnONP/GCE showed the best analytical characteristics with a linear dynamic range of 9.99×10 −8 –7.55×10 −4 M, detection limit of 1.37×10 −8 M and sensitivity of 17.00 μA mM −1 .
