Electrospun Polymer Mats for Controlled Drug Delivery in Wound Care
Researchers at the Henryk Niewodniczański Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) have developed electrospun polymer mats embedded with the antibacterial agent metronidazole, aiming to enhance wound healing through localized and controlled drug release. :contentReference[oaicite:2]{index=2}:contentReference[oaicite:3]{index=3}
Key Highlights:
- Electrospinning Technique: Utilizing electrospinning, a method that creates fine polymer fibers through an electrostatic field, the team produced mats capable of delivering drugs directly to wound sites.
- Controlled Drug Release: The mats are designed to release metronidazole gradually over several hours, ensuring sustained antibacterial action while minimizing systemic exposure.
- Structural Design: Two types of fiber structures were developed: homogeneous fibers and core-shell fibers, the latter using a coaxial needle to encapsulate the drug within a protective polymer shell.
- Optimal Fiber Dimensions: Studies determined that fiber diameters between 0.7 and 1.3 micrometers provide an adequate surface area for effective drug absorption and release.
- Storage Considerations: The mats can be stored for up to one month before application, after which the metronidazole may begin to crystallize, potentially affecting efficacy.
This innovative approach to wound care highlights the potential of electrospun polymer mats in delivering targeted therapy, reducing the risk of systemic side effects, and improving patient outcomes. The researchers suggest that this method could be adapted to carry other therapeutic agents, broadening its applicability in medical treatments. :contentReference[oaicite:18]{index=18}:contentReference[oaicite:19]{index=19}
