Synthesis, Characterization and Application of Advanced Antimicrobial Electrospun Polymers

Area of Science:

• Biomaterials Science
• Nanotechnology
• Infectious Disease Research

Background:

• High failure rates in musculoskeletal surgical repairs necessitate improved biomaterials.
• Hospital-acquired infections, especially from antibiotic-resistant bacteria (e.g., MRSA, MSSA), pose a significant global health threat.

Purpose of the Study:

• To synthesize and characterize advanced antimicrobial biocompatible electrospun polymers for medical implants.
• To develop specialized coatings for implants to combat Methicillin-resistant Staphylococcus aureus (MRSA) and Methicillin-sensitive Staphylococcus aureus (MSSA).

Main Methods:

• Utilized sol-gel process to create nanoparticle mixtures for antimicrobial coatings.
• Applied coatings to electrospun polycaprolactone (PCL) filaments.
• Characterized materials using spectroscopic (FTIR, Raman, NMR), microscopic (SEM, SEM-EDX), and tensile testing.

Main Results:

• Successfully developed and characterized antimicrobial coatings on PCL electrospun filaments.
• Demonstrated the potential of surface modification techniques combined with electro-spinning for implantable materials.

Conclusions:

• Electro-spinning technology and surface modification offer a promising approach for creating effective antimicrobial medical implants.
• The developed materials show potential for enhancing surgical repair success rates and reducing implant-associated infections.
