Abstract

Detection of Hydrogen Peroxide (H2O2) is of great importance in food manufacturing industry as it is used in aseptic packaging, where limitations of H2O2 present in food by the FDA are set to very low tolerances. It is important for living organisms to catalyze H2O2 at the cellular level to protect from oxidative damage due to reactive oxygen species resulting from the decomposition of H2O2. Prussian Blue (Iron(III) hexacyanoferrate(II)) has proven to be a good electrochemical sensor to detect H2O2 at increasingly low concentrations. The team aims to improve the detection of H2O2 using Prussian Blue (PB) in hopes of better understanding the formation of free radicals at a cellular level and the damage its decomposition products cause. Characterization of the PBNP is the starting point, it was performed using Atomic Force Microscopy. The synthesis of PB was performed using Potassium Ferrocyanide and Iron (III) Chloride in the presence of Hydrochloric Acid (HCl). The Characterization of the particles showed that the crystal structures need a better deposition method to allow for a layering of PB that will potentially increase sensitivity of the molecules towards H2O2, this will allow the team to move forward to the next step: Cyclic Voltammetry (CV) and PB’s electro sensitivity towards H2O2.
