Název v původním jazyce

Air-jet spinning of biocompatible polymeric nanofibers for wound dressings

Popis výsledku v původním jazyce

Air-jet spinning (or solution blowing) is a method of nanofibrous production using high-velocity gas flow of air or gas to transform drops of a polymer solution into fibers. The technology is promising for relatively safe applying nanofibers directly to wounds, in-situ application. In this work, air-jet spinning of polycaprolactone and poly(L-lactic acid) was performed utilizing a commercial airbrush for possible in situ application of skin wound dressings and for the production of flat samples of nanofibrous materials for further in-vitro testing. The optimal polymer solutions are introduced. The average fiber diameter of air-jet spun fibers was assessed using a scanning electron microscope. Cytotoxicity of fibrous mats and DNA quantification were investigated. Chemical changes in the structure of biodegradable polymers in fibrous mats were examined by Fourier- transform infrared spectroscopy. The degree of crystallinity was set via differential scanning calorimetry.
