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.

Summary of research results to be presented

Atomic Force Microscopy results require a different precipitation method, for the molecules of PBNP do not appear as closely together as the reference found in literature. The team aims to explore ways to improve deposition and synthesis of particles that are close together than the ones obtained. The PBNP obtained using the synthesis described in literature agree with the visual descriptions and the color observed, characteristic of the transition of Fe2+ to Fe3+, a visual confirmation of the existence of the PBNP. Though research needs to be performed to sharpen the experiment, it is safe to say that the team is moving in the right direction. The next objectives are a more thorough characterization using the same methods and researching the effect of sonication to allow the particles to clump together even closer.
