Collagen‐cellulose‐poly(l‐lactide) scaffold by electrospinning and plasma‐assisting fabrication for bone tissue engineering applications

Abstract

AbstractNovel biomaterials suitable for bone tissue engineering are currently in demand, and reformulating natural and synthetic biomaterials has caught scientists' attention. Cellulose and collagen have been utilized in biomedical fields. This research aimed to fabricate collagen‐cellulose‐poly(l‐lactide) (Col‐Cel‐PLL) scaffold using collagen, cellulose, and poly( l‐lactide) through electrospinning and radiofrequency plasma treatment and to examine the scaffold's physicochemical and biological properties. Fourier transform infrared spectroscopy revealed its chemistry, and scanning electron microscopy showed fine interconnecting microfibrous fibers; it was super‐hydrophilic with low crystallinity (25.59%) and great Young's modulus (163.940 ± 8.008 MPa), and it was reasonably degraded. Regarding biological properties, the scaffold was biocompatible by supporting cell attachment and viability. Cells on the Col‐Cel‐PLL produced high total protein levels and collagen deposition. However, the alkaline phosphatase activity was significantly low.
