- Magnetic nanoparticles are of great interest for research as they have a wide range of applications in biotechnology, environmental science, and biomedicine. Magnetic nanoparticles are ideal for magnetic separation, improving catalysis's speed and reusability by immobilizing enzymes. Nanobiocatalysis allows the removal of persistent pollutants in a viable, cost-effective and eco-friendly manner, transforming several hazardous compounds in water into less toxic derivatives. Iron oxide and graphene oxide are the preferred materials used to confer nanomaterials their magnetic properties for this purpose as they pair well with enzymes due to their biocompatibility and functional properties. This review describes the most common synthesis methods for magnetic nanoparticles and their performance of nanobiocatalysis for the degradation of pollutants in water. ¿ Magnetic nanomaterials have been synthesized for their application in nanobiocatalysis and treating groundwater. ¿ The most used method for magnetic nanoparticle preparation is the co-precipitation technique. ¿ Peroxidase and oxidase enzymes have great potential in the remotion of multiple contaminants from groundwater.
