Environment-Friendly Preparation and Characterization of Multilayered Conductive PVP/Col/CS Composite Doped with...

Area of Science:

• Biomaterials Science
• Tissue Engineering
• Regenerative Medicine

Background:

• Severe peripheral nerve injuries require advanced treatment alternatives to autografts.
• Nerve guide conduits are essential biomaterials for supporting nerve regeneration.
• Ideal conduits must be biocompatible, protective, and actively promote tissue recovery.

Purpose of the Study:

• To develop and characterize a novel, multilayered nerve guide conduit for peripheral nerve regeneration.
• To evaluate the biocompatibility and potential of the new conduit for injured nerve recovery.

Main Methods:

• Fabrication of a gradient-structured, multilayered biomaterial using electrospinning and electrospraying techniques.
• Characterization via FT-IR, SEM/EDS, and biodegradation studies.
• In vitro assessment of biocompatibility using 1321N1 human cell line and XTT assay.

Main Results:

• The novel biomaterial exhibited a gradient structure and was successfully modified with conductive nanoparticles.
• FT-IR, SEM/EDS, and biodegradation analyses confirmed material integrity and properties.
• Long-term cell culture demonstrated no cytotoxicity, with cells maintaining healthy morphology.

Conclusions:

• The developed polyvinylpyrrolidone, collagen, and chitosan-based nerve guide conduits show high potential for nerve tissue regeneration.
• This biomaterial offers a promising alternative for the treatment of injured peripheral nerves.
