Immobilization of Candida antarctica lipase B on PEGylated poly(urea-urethane) nanoparticles by step miniemulsion polymerization

- CalB lipase was immobilized in PEGylated poly(urea-urethane) nanoparticles by step miniemulsion polymerization.
- Crodamol showed a protective effect on the enzyme.
- PEGylated poly(urea-urethane) nanoparticles as a new alternative to immobilization support.
- A promising immobilization method was developed.
