Bioactive materials, able to induce hydroxyapatite precipitation in contact with body fluids, are of great interest for their bone bonding capacity. . The aim this paper is compare bioactive materials different surface features verify the mechanisms action and relationship kinetics type precipitated over time. Four treatments Ti/Ti6Al4V alloy a glass were selected mechanism bioactivity supposed each them. Apart from conventional techniques (FESEM, XPS EDX), less common characterizations...
Surface potential of biomaterials is a key factor regulating cell responses, driving their adhesion and signaling in tissue regeneration. In this study we compared the surface zeta smooth porous electrospun polycaprolactone (PCL) fibers, as well PCL films, to evaluate significance bone The ' fibers was controlled by applying positive negative voltage polarities during electrospinning. properties different films were measured using X-ray photoelectron spectroscopy (XPS) Kelvin probe force...
Surface properties of biomaterials (e.g., roughness, chemical composition, charge, wettability, and hydroxylation degree) are key features to understand control the complex interface phenomena that happens upon contact with physiological fluids. Numerous physico-chemical techniques can be used in order investigate depth these crucial material features. Among them, zeta potential measurements widely for characterization colloidal suspensions, but actually poorly explored study solid surfaces,...
It is widely recognized that surface nanotextures applied on a biomaterial can affect wettability, protein absorption and cellular and/or bacterial adhesion; accordingly, they are nowadays of great interest to promote fast osseointegration maintain physiological healing around biomedical implants. In order be suitable for clinical applications, must not only safe effective, but also, should produced through industrial processes scalable real devices with sustainable costs: this often barrier...
Surface texturing is widely investigated for the modulation of surface properties and biological response implantable materials. Laser a green technology obtainment specific patterns without employment toxic chemicals. In present research, picosecond laser treatment was applied to commercially pure titanium Ti6Al4V alloy aligned grooves characterized by micrometric width spacing but submicrometric depth promote fibroblast alignment discourage bacterial adhesion. topography roughness...
The interest in environmentally friendly coatings is rising to substitute for the oil-derived materials coating industry. In present study, natural tannic acid (TA) investigated as an additive epoxidized soybean oil-based (ESO) coating. TA solutions propylene carbonate at two different concentrations were prepared and added ESO matrix with weight ratios. UV-curing process of was deeply assessed through real-time Fourier Transform Infrared (FTIR) spectroscopy Differential Scanning photo...
Nowadays, there is a large amount of research aimed at improving the multifunctional behavior biomaterials for bone contact, including concomitant ability to induce apatite formation (bioactivity), fast and effective osteoblasts colonization, antibacterial activity. The aim this study develop bioactive surfaces (Ti6Al4V alloy silica-based glass) by chemical doping with strontium and/or silver ions. were characterized Scanning Electron Microscopy equipped Energy Dispersive X ray Spectroscopy...
Corrosion is recognized as an unavoidable phenomenon and steel, particularly carbon strongly susceptible to corrosion. damages cause serious material, energy, economic losses well negative impacts on the environment. As a result, research interest has been focused development of effective corrosion prevention strategies. However, some most commonly used inhibitors, such chromates pyridines, are harmful human environmental health. Polyphenols natural, non-toxic, biodegradable compounds from...
