Electrospun fibers based on the thermoresponsive polymer poly(N-isopropylacrylamide) (PNIPAAm), poly(l-lactic acid-co-?-caprolactone) (PLCL), and the antibiotic ciprofloxacin (CIF) were prepared. The water contact angle of fibers made from a blend of PNIPAAm and PLCL changed dramatically when the temperature was increased above 32 oC. Sustained release of CIF from the formulations was observed over {\ensuremath{>}} 200 h. Moreover, L929 fibroblasts could proliferate on the fibers, indicating their biocompatibility. The CIF-loaded fibers were found to have potent antibacterial activity against E. coli and S. aureus. In vivo tests on rats indicated that CIF-loaded thermosensitive fibers have enhanced healing performance compared to CIF-loaded PLCL fibers or a commercial gauze. Electrospun PNIPAAm/PLCL fibers loaded with CIF thus have great promise in the development of new wound dressing materials.}, url = {http://dx.doi.org/10.1016/j.msec.2017.04.058} }
