Cellulose-based composite scaffolds for bone tissue engineering and localized drug delivery

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Polymer Chemistry

Background:

• Natural bone has limited regeneration capacity, especially for large defects.
• Tissue engineering offers a promising alternative to traditional bone repair methods.
• Cellulose and its derivatives are attractive biomaterials for bone regeneration.

Purpose of the Study:

• To review cellulose-based composite scaffolds for bone tissue engineering.
• To explore their application in localized drug delivery and bone regeneration.
• To highlight their properties and classifications.

Main Methods:

• Review of literature on cellulose-based composite scaffolds.
• Classification of scaffolds into cellulose-organic, cellulose-inorganic, and cellulose-organic/inorganic composites.
• Analysis of physicochemical, mechanical, and biological properties.

Main Results:

• Cellulose-based scaffolds exhibit non-toxicity, biocompatibility, and biodegradability.
• They are cost-effective and derived from renewable resources.
• These scaffolds facilitate the delivery of growth factors and antibiotics for bone repair.

Conclusions:

• Cellulose-based composite scaffolds are versatile for bone tissue engineering.
• They offer significant potential for bone defect repair and regeneration.
• Further research into their properties can optimize clinical applications.
