Preparation of core-shell magnetic polydopamine/alginate biocomposite for Candida rugosa lipase immobilization

- Core-shell magnetic polydopamine/alginate biocomposite was synthesized.
- The superparamagnetic mPDA/ADA possesses a well-defined structure.
- The mPDA/ADA was used for enzyme immobilization without any toxic coupling reagent.
- The mPDA/ADA possesses good biocompatibility for enzyme immobilization.
- The ICRL shows excellent environmental stability and catalytic activities.
