To fabricate ideal wound dressings without involvement of chemical processes is attracting the interest in clinical requirements. Nano-maghemite-incorporated chitosan-coated cellulose porous membranes were prepared and evaluated in terms of those critical requirements as wound dressings. The composite membranes were characterized using elemental analysis, scanning electron microscopy (SEM), Fourier...
In this work, magnetic Fe3O4 nanoparticles (NPs) were utilized to improve the mechanical and antibacterial properties of chitosan (CS)/gelatin (GE) composite nanofiber membranes. Homogeneous Fe3O4/CS/GE nanofibers were electrospun successfully. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images confirmed the presence of well-dispersed Fe3O4 NPs in the composite nanofibers...
A combination of a superior hygroscopic capacity, mechanical strength and antibacterial activity is required for a wound dressing material. To this end, a facile and green technique to prepare porous composite membranes with a sandwich structure is developed here through surface coating of a ready-made cellulose membrane with chitosan. The cellulose membrane endows the composite material with a porous...
