Chitosan-graft-beta-cyclodextrin scaffolds with controlled drug release capability for tissue engineering...

Area of Science:

• Biomaterials Science
• Tissue Engineering
• Drug Delivery Systems

Background:

• Biodegradable scaffolds are crucial for tissue regeneration.
• Chitosan-based materials are widely investigated for biomedical applications.
• Beta-cyclodextrin enhances drug loading and controlled release properties.

Purpose of the Study:

• To develop and characterize biodegradable chitosan-g-beta-cyclodextrin (chit-g-beta-CD) scaffolds.
• To evaluate their potential as synthetic extracellular matrices for tissue healing.
• To investigate their drug loading and controlled release capabilities.

Main Methods:

• Freeze-drying method for scaffold fabrication.
• Assessment of scaffold morphology, swelling, and drug release kinetics.
• In vitro cytotoxicity testing using MTT assay on L929 fibroblasts.

Main Results:

• Scaffold properties were dependent on cross-linking density.
• Chit-g-beta-CD scaffolds exhibited slower ketoprofen release compared to chitosan scaffolds.
• No significant cytotoxicity was observed for chit-g-beta-CD scaffolds cross-linked with 0.01 M glutaraldehyde.

Conclusions:

• Chit-g-beta-CD scaffolds are promising biodegradable materials for tissue regeneration.
• These scaffolds possess controlled drug release capabilities.
• They create a favorable environment for tissue healing and regeneration.
