제목 Biomimetic chitosan–polyvinyl pyrrolidone films for medical application
초록 Lotus-leaf-like structured chitosan–PVP films were prepared using a solution casting method with dodecyltrichloro-immobilized SiO2 nanoparticles. We evaluated whether the lotus-leaf-like structured chitosan–PVP films could be applied as postsurgical anti-adhesion barriers. A recovery test using a tensile strength testing machine and mea-surement of crystallinity using X-ray diffraction indicated that films with 75% PVP were the optimalcomposition of the chitosan–PVP films. Also, dodecyltrichloro-immobilized SiO2nanoparticles were syn-thesized and sprayed on the film after pretreatment with the instant bio-glue. Analysis of cell adhesion,proliferation, and anti-thrombus efficiency were performed via a WST assay, field emission scanningelectron microscopy, and hemacytometry. The contact angle with the lotus-leaf-like surface was ofapproximately 150◦. Furthermore, the l-chitosan–PVP film yielded a lower cell and platelet adhesion rate(around less than 4%) than that yielded by the untreated film.
