Stabilization of collagen waste fibers using SPION.
(a) Schematic showing the interaction of collagen waste fibers and SPION nanoparticles to yield collagen-SPION nanobiocomposite (ratio of collagen and SPION by weight is 100/50%; figure (a) not drawn to scale); (b) DSC traces of pristine collagen and collagen-SPION nanobiocomposite, in the figure Endo down (inset shows the photograph of collagen-SPION composite pellet with 10 mm dia); (c) XRD patterns of pristine collagen and collagen-SPION nanobiocomposite.
