Surface Modification of Electrospun Nanofibers for Biomedical Use
Research Guide
What is Surface Modification of Electrospun Nanofibers for Biomedical Use?
Surface modification of electrospun nanofibers involves plasma treatment, chemical grafting, and coating techniques to enhance hydrophilicity, bioactivity, and antifouling properties for biomedical applications.
Researchers apply these methods to reduce protein adsorption and bacterial adhesion on nanofiber scaffolds used in tissue engineering and implants. Key reviews cover functionalization strategies for drug delivery and regenerative medicine. Over 1000 papers cite foundational works like Yoo et al. (2009) with 1066 citations.
Why It Matters
Surface-modified electrospun nanofibers improve implant integration by minimizing foreign body reactions, as shown in Yoo et al. (2009) for tissue engineering scaffolds. Dhandayuthapani et al. (2011, 1730 citations) highlight how tailored surfaces support cell adhesion in regenerative medicine. These modifications enhance wound healing devices, per Tottoli et al. (2020, 1201 citations), and enable controlled drug release in alginate composites (Sun and Tan, 2013, 1329 citations).
Key Research Challenges
Maintaining Nanofiber Integrity
Surface treatments like plasma can degrade electrospun fiber morphology and mechanical strength. Zhang et al. (2004, 1062 citations) note gelatin fiber alterations post-modification. Balancing modification depth with structural stability remains difficult.
Achieving Uniform Functionalization
Chemical grafting often leads to uneven surface coverage on nanofibers due to high surface area. Yoo et al. (2009, 1066 citations) discuss coating inconsistencies affecting bioactivity. Scalability for clinical implants poses additional hurdles.
Long-term Biocompatibility
Modified surfaces may lose antifouling properties over time in vivo, promoting bacterial adhesion. Tottoli et al. (2020) report variable outcomes in wound healing scaffolds. Predicting degradation and biofouling requires advanced testing (Dhandayuthapani et al., 2011).
