Preparation of Nanoparticle-containing Aligned Collagen Fibers for Dense Connective Tissue Repair and Regeneration
Published online by Cambridge University Press: 19 April 2012
Abstract
Nanoparticles (NPs) loaded with human platelet-derived growth factor (h-PDGF) were prepared and characterized. These NPs were co-assembled with collagen to form highly aligned NP-collagen composite fibers by using an electrochemical process. PDGF can be released gradually from either NPs or aligned NP-collagen fibers. This investigation demonstrated a novel way to fabricate highly aligned composite fibers, which can locally release a growth factor in a controlled and gradual manner, potentially avoiding the fast clearance of the growth factor from the implantation site. Thus, the aligned NP-collagen fiber is a novel and promising implantation material for tendon/ligament repair and regeneration.
