Coatings were grown on the AZ31 Mg alloy by a hard anodizing process in hot glycerol phosphate-containing electrolyte. Anodizing conditions optimized, maximizing corrosion resistance estimated impedance measurements carried out Hank's solution at 37 °C. A post annealing treatment (350 °C for 24 h) allowed us to further enhance of coatings mainly containing magnesium phosphate according energy-dispersive X-ray spectroscopy and Raman analyses. Gravimetric revealed hydrogen evolution rate...
Scaffolds suitable for tissue engineering applications like dermal reconstruction were prepared by Thermally Induced Phase Separation (TIPS) starting from a ternary solution PLLA/dioxane/water. The experimental protocol consisted of three consecutive steps, first quench the homogeneous to an appropriate demixing temperature (within metastable region), holding stage given residence time, and final low unstable region). A large variety morphologies, in terms average pore size interconnection,...
Abstract Electrospun scaffolds exhibiting high physical performances with the ability to support cell attachment and proliferation are attracting more scientific interest for tissue engineering applications. The inclusion of inorganic nanoparticles such as nanosilica nanoclay into electrospun biopolymeric matrices can meet these challenging requirements. silica clay incorporation polymeric nanofibers has been reported enhance improve mechanical properties well osteogenic scaffolds. In this...
Bio-based, biodegradable polymers can dramatically reduce the carbon dioxide released into environment by substituting fossil-derived in some applications. In this work, prototypes of trays for aquaculture applications were produced via injection molding using a polymer, Mater-Bi®. A characterization carried out calorimetric, rheological and mechanical tests revealed that polymer employed shows properties suitable production tools to be used Moreover, samples subjected biodegradation test...
A critical obstacle encountered by tissue engineering is the inability to maintain large masses of living cells upon transfer from in vitro culture conditions host vivo. Capillaries, and vascular system, are required supply essential nutrients, including oxygen, remove waste products provide a biochemical communication “highway”. The successful use tissue-engineered constructs currently limited thin or avascular tissues, such as skin cartilage, for which post-implantation neo-...
ABSTRACT Thermally induced phase separation is a fabrication technique for porous polymeric structures. By means of easy‐to‐tune processing parameters, such as system composition and demixing temperature, vast latitude average pore dimensions, size distributions, morphologies can be obtained. The relation between temperature morphology was demonstrated via cloud point curve measurement foams with controlled thermal protocols, the model poly‐ l ‐lactide–dioxane–water. obtained at lower than...
Teeth extractions are often followed by alveolar bone reabsorption, although an adequate level of is required for reliable rehabilitations dental implants. Leukocyte and platelet-rich fibrin (L-PRF) has been widely applied in regenerative procedures with antibiotic antioxidant agents could play essential role hard soft tissue healing. In this work, a nanocomposite (Sponge-C-MTR) consisting hyaluronate-based sponge loaded metronidazole (MTR) nanostructured lipid carriers containing curcumin...
Hybrid porous scaffolds composed of both natural and synthetic biopolymers have demonstrated significant improvements in the tissue engineering field. This study investigates for first time fabrication route characterization poly-L-lactic acid blended with polyhydroxyalkanoate up to 30 wt%. The hybrid were prepared by a thermally induced phase separation method starting from ternary solutions. microstructure structures was analyzed scanning electron microscopy related blend composition....
Bilayer scaffolds could provide a suitable topology for osteochondral defect repair mimicking cartilage and subchondral bone architecture. Hence, they facilitate the chondro- osteogenic lineage commitment of multipotent mesenchymal stromal cells (MSCs) with hydroxyapatite, major inorganic component bone, stimulating osteogenesis. Highly porous poly-L-lactic acid (PLLA) two layers different pore sizes (100 250 µm) hydroxyapatite (HA) supplementation were established by thermally induced phase...
This study aims to demonstrate the possibility of incorporating a natural antioxidant biomolecule into polymeric porous scaffolds. To this end, Poly-l-Lactic Acid (PLLA) scaffolds were produced using Thermally Induced Phase Separation (TIPS) technique and additivated with different amounts rosmarinic acid (RA). The scaffolds, diameter 4 mm thickness 2 mm, characterized multi-analytical approach. Specifically, Scanning Electron Microscopy analyses demonstrated presence an interconnected...
