Abstract

This investigation aims to immobilize peroxidase onto 3-aminopropyltriethoxysilane (APTES)-functionalized MgFe₂O₄ magnetic nanoparticles to increase enzyme stability, efficiency, and recyclability. The synthesized samples were analyzed using X-ray diffraction, Fourier transform infrared spectroscopy, Thermogravimetric analysis, Vibrating sample magnetometer, and Scanning electron microscopy. The free and immobilized peroxidase were examined against different pH and temperatures as well as storage time and reuse. The immobilized peroxidase maintained 52 % of its initial activity after 10 consecutive measurements thanks to easy magnetic separation. In addition, antioxidant activity was increased by immobilizing the peroxidase to the MgFe₂O₄ magnetic nanoparticles. Congo red dye removal for peroxidase immobilized MgFe₂O₄-APTES was found to be 98.6 % for 240 min. Also, it showed approximately two times more dye decolorization efficiency compared to MgFe₂O₄ and APTES modified MgFe₂O₄. Finally, the immobilized peroxidase was studied by a decolorization study of congo red. So, we believe that the immobilized peroxidase on magnetic nanoparticles reported in this study may be utilized in diverse biotechnology, industrial, and environmental practices.

期刊介绍： Biophysical Chemistry publishes original work and reviews in the areas of chemistry and physics directly impacting biological phenomena. Quantitative analysis of the properties of biological macromolecules, biologically active molecules, macromolecular assemblies and cell components in terms of kinetics, thermodynamics, spatio-temporal organization, NMR and X-ray structural biology, as well as single-molecule detection represent a major focus of the journal. Theoretical and computational treatments of biomacromolecular systems, macromolecular interactions, regulatory control and systems biology are also of interest to the journal.
