Biodegradable nanomats produced by electrospinning: expanding multifunctionality and potential for tissue engineering

Area of Science:

• Nanotechnology
• Biomaterials Science
• Tissue Engineering

Background:

• Nanofibers (n-fibers) and nanoscaffolds (n-scaffolds) produced via electrospinning are gaining traction for tissue engineering applications.
• These structures closely resemble the natural extracellular matrix (ECM) due to their nanoscale fibrous architecture.
• Improvements in electrospinning allow for the creation of submicron fibers from biodegradable polymers, leading to multifunctional, drug-releasing, and bioactive scaffolds.

Purpose of the Study:

• To review the electrospinning process for creating nanoscaffolds for tissue engineering.
• To discuss factors influencing nanostructure properties: substrate, apparatus, and environment.
• To highlight the characterization and applications of developed nanoscaffolds, particularly in blood vessel engineering.

Main Methods:

• Review of electrospinning techniques for nanofiber and nanoscaffold fabrication.
• Analysis of factors affecting electrospinning: substrate, apparatus, and environmental conditions.
• Evaluation of nanoscaffold cytocompatibility and use in tissue engineering constructs, including blood vessel development.

Main Results:

• Electrospinning enables the production of nanoscaffolds with structures similar to natural ECM.
• Nanoscaffolds demonstrate cytocompatibility and potential for tissue engineering constructs.
• Specific focus on the application of nanoscaffolds in developing blood vessels.

Conclusions:

• Electrospinning is a key technique for developing advanced nanoscaffolds for tissue engineering.
• Further research into multifunctional scaffolds for controlled drug delivery and various tissue types is warranted.
• The convergence of nanotechnology, drug release, and tissue engineering offers potential solutions for scaffold limitations in vivo.
