 This research paper presents a novel approach to immobilizing lipase onto magnetic iron oxide nanoparticles using polydopamine films. The authors found that this method resulted in higher lipase loading capacities and improved stability compared to other methods. Additionally, they were able to recover up to 70% of the original activity after multiple cycles of enzymatic reaction and magnetic separation. This method is therefore highly promising for industrial applications such as large-scale production of biomaterials. This article was authored by Hila Hong, Rivera Hoseiji, Ren Yu Hong, and others.
