A feasible approach toward bioactive glass nanofibers with tunable protein release kinetics for bone scaffolds

- Fine bioactive glass (BG) nanofibers with controlled protein release kinetics.
- The increased water content enhances the SiOSi network integrity of sol-gel BG fibers.
- The 'anchoring' effect of the apatite layers formed prohibits protein releasing.
- More crystalline apatite layer induces sustained release kinetic of protein molecules.
