A biocomposite of collagen nanofibers and nanohydroxyapatite for bone regeneration.
This work aims to design a synthetic construct that mimics the natural bone extracellular matrix through innovative approaches based on simultaneous type I collagen electrospinning and nanophased hydroxyapatite (nanoHA) electrospraying using non-denaturating conditions and non-toxic reagents. The morphological results, assessed using scanning electron microscopy and atomic force microscopy (AFM...
متن کاملBiodegradable nanofibers-reinforced microfibrous composite scaffolds for bone tissue engineering.
Native bone extracellular matrix (ECM) is a complex hierarchical fibrous composite structure, resulting from the assembling of collagen fibrils at several length scales, ranging from the macro to the nanoscale. The combination of nanofibers within microfibers after conventional reinforcement methodologies seems to be a feasible solution to the rational design of highly functional synthetic ECM ...
متن کاملPresentation of a novel model of chitosan- polyethylene oxide-nanohydroxyapatite nanofibers together with bone marrow stromal cells to repair and improve minor bone defects
Objective(s):Various methods for repairing bone defects are presented. Cell therapy is one of these methods. Bone marrow stromal cells (BMSCs) seem to be suitable for this purpose. On the other hand, lots of biomaterials are used to improve and repair the defect in the body, so in this study we tried to produce a similar structure to the bone by the chitosan and hydroxyapatite. Materials and Me...
متن کاملEvaluation of Polyether sulfone/nanohydroxyapatite nanofiber composite as bone graft materials
Nanofiber mats of polyether sulfone/nano hydroxyapatite (PES/nHA) were prepared by electrospinning technique. The fabricated composites were characterized using FTIR, XRD and SEM. The composite nanofiber mats were subjected to in vitro biological studies namely bioactivity, haemocompatibility and cytocompatibility. The XRD analysis showed an increase in the amorphous nature of the composite wit...
متن کاملInvestigation of Biological Property of Nanohydroxyapatite Materials
As it is known, the ceramic and metallic materials, such as Ni-Cr and Co-Cr alloy serve often as a fixed dental materials of restoration in human bones, teeth and vascular stents, but they have a lot of shortcomings, such as they can result in Ni and Cr hypersusceptibility of men and ion exchange between the material and tooth, which lead the distortion and discoloration of the gingival edge an...
