Polycaprolactone (PCL) nanofibers (PCL-NF) with uniform fibrous structure were fabricated by electrospinning. However, PCL-NF has hydrophobic surface, lacks functional groups and hence it is not a good substrate for cell adhesion. To improve the adhesion, surfaces modified low pressure RF discharge plasma treatment using monomer such as acrylic acid or oxygen gas. The treated PCL-NFs improved wettability proliferation.
Magnesium (Mg) is light, has biocompatibility, and mechanical properties close to those of natural bone. However, pure Mg severely corrodes in a physiological environment, which may result fracture prior substantial tissue healing. In this study, the surface was modified by depositing thin polymeric film containing COOH, NH 2 , OH groups through plasma polymerization acrylic acid, allyl amine, alcohol order improve its anticorrosion bioactive properties. The –COOH group had significant...
An appropriate interaction between implanted materials and the surrounding tissue is essential for successful implantation. Titanium (Ti) some of its alloys have been used in dentistry orthopedics as a substitutive material hard tissue, such teeth or natural bone. Nevertheless, metal ions released from titanium alloy implants adverse biological effects on tissues cells. Secretory leukocyte protease inhibitor (SLPI) promotes cell migration, proliferation wound healing. FAK ERK1/2 signaling...
In the present study, electrochemical deposition of hydroxyapatite substituted with magnesium and strontium on Ti-6Al-4V alloy have investigated. Mg Sr-doped HAp was coated using subsequently pulsed process at 85 °C in solution contained Ca, Mg, Sr, P ion. The morphology Mg/Sr-HAp formed implant investigated scanning electron microscopy X-ray diffraction. grain size XRD intensity decreased Mg2+ Sr2+ ions. initial current density changed addition Sr ion concentration when constant voltage...
Abstract Dental implant systems are subject to failure in the screw connection part which can occur due loosening or fracture. For solving problem of loosening, some researchers had carried out TiN(titanium nitride) and WC(tungsten carbide) coating on abutment screw, while fatigue may still be not researched as an issue materials. In this study, test was performed estimate fracture coated for system according ISO 14801. purpose, TiN WC film using EB-PVD sputtering, respectively. test,...
Nano- and micro-phase HA film formed on TiO2 nano-network surface by simple electrochemical treatment. The range of lateral pore size the network specimen was about 10-120 nm Ti anodized in 5 M NaOH solution at 0.3 A for 10 min. Nano-network were this anodization step which acted as templates anchorage growth during subsequent pulsed deposition process 85 degrees C. phase morphologies deposits influenced electrolyte concentration. nano needle-like precipitates under low SBF concentration...
Biomaterials developed for controlled drug delivery have demonstrated excellent results in the present study. A biomaterial prepared using hydroxyapatite (HAp) was shown to a hollow structure with presence of interconnected pores house carriers. The poly(lactic-co-glycolic acid) particles were used as carriers loaded dexamethasone, corticosteroid that is known promote osteoinduction. surface modified polyethyleneimine, and then conjugated HAp granules. granules had on both their inner outer...
The preparation of a dual-drug-eluting stent was investigated by grafting α-lipoic acid (ALA) with abciximab on bare metal coated polymer layer plasma polymerization 1,2-diaminocyclohexane (DACH). carried out at 100 W for 5 min and then 60 15 min. ALA were grafted to the after activating in 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide methiodide. amounts released affected pattern. When reaction proceeded mixed solution abciximab, amount much larger than that not only but also ALA, small....
