” The rapid and accurate detection of low levels of hydrogen peroxide (H₂O₂) is of great importance as it is an indispensable intermediate product of several highly selective oxidases and an essential mediator in clinical, environmental, food and industrial analysis. In the current work, a novel biosensor was fabricated based on the sensitivity of hemoglobin (Hb) towards H₂O₂, by integrating two different sensing technologies on the same Hb modified ZnO/Metglas electrode, namely cyclic voltammetry and magnetoelastic resonance, whilst we try to compare them. The addition of H₂O₂ in PBS buffer, revealed intense electrocatalytical currents caused by the oxidation of the immobilized reduced Hb and simultaneously the magnetoelastic ribbon worked as a microbalance to detect shifts in mass loads on immobilized Hb. “
