Development of a Lidocaine-Loaded Alginate/CMC/PEO Electrospun Nanofiber Film and Application as an Anti-Adhesion Barrier

Surgery, particularly open surgery, is known to cause tissue/organ adhesion during healing. These adhesions occur through contact between the surgical treatment site and other organ, bone, or abdominal sites. Fibrous bands can form in unnecessary contact areas and cause various complications. Consequently, film- and gel-type anti-adhesion agents have been developed. The development of sustained drug delivery systems is very important for disease treatment and prevention.*

In “Development of a Lidocaine-Loaded Alginate/CMC/PEO Electrospun Nanofiber Film and Application as an Anti-Adhesion Barrier” Seungho Baek, Heekyung Park, Youngah Park, Hyun Kang and Donghyun Lee describe how the drug release behavior was controlled by crosslinking lidocaine-loaded alginate/carboxymethyl cellulose (CMC)/polyethylene oxide (PEO) nanofiber films prepared by electrospinning.*

Lidocaine is mainly used as an anesthetic and is known to have anti-adhesion effects.*

Based on the results presented in the article, this study shows that the drug release behavior can be controlled by using CaCl2 as a nontoxic crosslinking agent to produce a good anti-adhesion barrier that can prevent unnecessary tissue adhesion at a surgical site.*

The authors selected atomic force microscopy (AFM) using NANOSENSORS™ PointProbe® Plus PPP-NCHR AFM cantilevers to analyze the electrospun films.*
