Abstract

The use of green materials in biomedical and bioengineering applications has significantly expanded in recent years. In this study, we utilized egg white (EW) as an abundant and cost-effective green material, blended with polycaprolactone/gelatin (PCL/Gel), to fabricate an electrospun scaffold. The fabricated samples underwent comprehensive physicochemical characterization, including SEM, FT-IR spectroscopy, tensile assay, and contact angle measurement. These optimized samples were subsequently employed for cell culture experiments. The average diameter of the prepared nanofibers ranged from 215.9 to 434.1 nm. FT-IR and DSC assays confirmed the physical blending of EW, PCL, and Gel without any occurrence of new chemical reactions. The contact angle test demonstrated a decrease in scaffold hydrophilicity from 26.25° to 116.5° with an increase in EW content within the PCL/Gel blend (0%-15%). Notably, the electrospun PCL/Gel nanofibrous mat containing 10% EW exhibited enhanced bioactivity compared to other samples with varying amounts of EW. Consequently, incorporating 10% EW into PCL/Gel nanofibers can significantly improve the efficiency of fibroblast culture. This research introduces a novel nanofibrous scaffold for skin tissue engineering, incorporating Gel and EW as low-cost and readily available materials, with great potential for various biological applications. © 2024 IOP Publishing Ltd.
