Abstract
AbstractThis study focused on 3D printing‐preparation of novel biomaterials based on fish scale collagen and the following plant extracts: Eclipta alba L. Hassk leaf (EA), Piper betle L. leaf (PB), Perilla frutescens L. Britt leaf (PF), and Styphnolobium japonicum L. Schott flower bud (SJ). The characterizations of the obtained biomaterials were analyzed using infrared spectroscopy and stereo microscopy. Additionally, assessments of the biomaterials were conducted on the water contact angle, simulated body fluid contact angle, scratch resistance, color changes, and swelling degree in simulated body fluid. Furthermore, in‐vitro blood clotting time and the anti‐inflammatory ability of these biomaterials were also performed. The results indicated that the plant extracts contributed to modifying collagen, significantly improving the scratch resistance and water contact angle of the collagen/plant extract biomaterials. The plant extracts were dispersed consistently with the collagen matrix, impacting the vibrations of specific functional groups of collagen. Collagen/plant extract dressings exhibited great biocompatibility and anti‐inflammatory. The in‐vitro tests demonstrated that the ethanol EA extract notably enhanced the hemostatic effectiveness of collagen, suggesting the potential of collagen/plant extract biomaterials in hemostatic applications.
