Polymeric Composite including Magnetite Nanoparticles for Hydrogen Peroxide Detection

The combination of a biopolymer and a conductive polymer can produce new materials with improved physico-chemical and morphological properties that enhance their use as sensors. Magnetite nanoparticles (MN) can be further introduced to these new matrices to improve the analytical performance. This s...
