Abstract The covalent grafting of poly (sodium 4- styrene sulfonate) on poly (ɛ-caprolactone) was proved to enhance the bioactivity of this polymer. The aim of this article was to perform kinetic studies of the activation and grafting processes and illustrate the influence of several parameters on the grafting rate and on the degradation of the polymer substrate. Results showed that the active groups created on poly (ɛ-caprolactone) surface by ozonation reach a maximum concentration after a shor...

Abstract Silicone-based materials are largely used in plenty of fields, especially in the biomedical field as implantable devices for surgery purposes. However, due to recent issues, the safety of the material has been reconsidered. In this work, we aim to graft a bioactive polymer on silicone breast implants shell surface to allow better integration of the implant inside the body and also a decrease of the bacterial adhesion. To functionalize silicone material, we develop a simple method to fir...

Background: The delivery of therapeutic genes in sites of articular cartilage lesions using non-invasive, scaffold-guided gene therapy procedures is a promising approach to stimulate cartilage repair while protecting the cargos from detrimental immune responses, particularly when targeting chondroreparative bone marrow-derived mesenchymal stromal cells in a natural microenvironment like marrow aspirates. Methods: Here, we evaluated the benefits of providing a sequence for the cartilage-specific ...

Abstract In this paper, the microstructure and biological properties through osteoblast cell viability and morphology study of Nano Crystalline Diamond (NCD) films deposited on Ti and TiAl6V4 substrates using a Distributed Antenna Array (DAA) microwave system are investigated. The morphology, purity and microstructure of such NCD coatings are comparable to those usually obtained on silicon wafers in the considered reactor, whereas the surface roughness is much higher due to the high roughness of...

Abstract This study is part of a new trend in the metallic biomaterials field that searches to use the titanium beta alloys with recognized bulk and surface properties for better biological response. Ti15Mo alloy (wt%) had it surface modified by TiO2 nanotubes growth using the anodic oxidation method and grafted with poly(sodium styrene sulfonate) (PNaSS). The motivation behind the combination of these techniques was to promote a surface, which enables better osteointegration associated with ant...

The purpose of this study is to present the poly(caprolactone) (PCL) functionalization by the covalent grafting of poly(sodium styrene sulfonate) on electrospun scaffolds using the “grafting from” technique and evaluate the effect of the coating and surface wettability on the biological response. The “grafting from” technique required energy (thermal or UV) to induce the decomposition of the PCL (hydro)peroxides and generate radicals able to initiate the polymerization of NaSS. In addition, UV i...

With the growing number of anterior cruciate ligament (ACL) ruptures and the increased interest for regenerative medicine procedures, many studies are now concentrated on developing bioactive and biodegradable synthetic ligaments. For this application, the choice of raw materials with appropriate physicochemical characteristics and long-term degradation features is essential. Polycaprolactone (PCL) has the advantage of slow degradation that depends on its molecular weight. This study evaluates t...
