title: Coaxially electrospun micro/nanofibrous poly(epsilon-caprolactone)/eggshell-protein scaffold.
abstract: Eggshell membrane (ESM) has potential as a natural scaffold because of its highly porous structure and good biocompatibility. To mimic its structure and surface properties, soluble eggshell membrane protein (SEP) was extracted from ESM and electrospun with a biodegradable polymer, poly(epsilon-caprolactone) (PCL). SEP/PCL micro/nanofibers were fabricated using a coaxial electrospinning process with a dual nozzle and an auxiliary cylindrical electrode. The fiber web was characterized using the water contact angle, pore-size distribution, mechanical properties and cellular behavior. The SEP/PCL web, which demonstrated the feasibility of producing a scaffold with adequate hydrophilicity, suitable pore size and good mechanical properties compared to a pure PCL micro/nanofiber web, exhibits the ability to mimic a natural biomaterial.
