Hypothesis
Can electrospun nanofibers effectively release bacteriocins while retaining their antimicrobial activity?
Conclusion
Electrospun nanofibers can effectively deliver bacteriocins and retain their antimicrobial activity, making them suitable for infection control applications.
Supporting Evidence
- Bacteriocins were released from nanofibers with a high initial burst and retained 88% of their antimicrobial activity at 37 °C.
- The PEO 90:PDLLA 10 blend released the highest concentration of antimicrobial peptides.
- Nanofibers showed stability for at least 8 days in PBS buffer without significant structural changes.
Takeaway
This study shows that tiny fibers can be used to carry special proteins that fight germs, helping to keep us safe from infections.
Methodology
Bacteriocins were electrospun into nanofibers made from PDLLA and PEO, and their release and antimicrobial activity were evaluated in vitro.
Limitations
The study primarily focuses on in vitro results, which may not fully represent in vivo conditions.
