Mussel-inspired adhesive and transferable free-standing films by self-assembling dexamethasone encapsulated BSA nanoparticles and vancomycin immobilized oxidized alginate

- A free-standing film is obtained by assembling oxidized Alg and Chi coated BSA NP.
- The films can be detached from substrates and transferred to non-fouling surfaces.
- The films enable the dual release of dexamethasone and vancomycin.
- The films have excellent osteoinductivity and antibacterial activity.
