Ultrathin core-sheath fibers for liposome stabilization

- Small unilamellar vesicles (SUVs) in the diameter about 50 nm were prepared and stabilized by sodium hyaluranate (HA-Na) aqueous solution.
- Liposome-loaded core-sheath HA-Na/PVP ultrathin fibers were produced by coaxial electrospinning.
- SUVs dispersed in the core HA-Na matrix and were in the elliptical shape.
- SUVs were stable within the core-sheath fibers and can be rehydrated in water.
