Abstract Electrophoretic deposition process (EPD) was successfully used for obtaining graphene (Gr)‐reinforced composite coating based on hydroxyapatite (HAP), chitosan (CS), and antibiotic gentamicin (Gent), from aqueous suspension. The performed as a single step at constant voltage (5 V, time 12 min) pure titanium foils. influence of examined through detailed physicochemical biological characterization. Fourier transform infrared spectroscopy, field emission scanning electron microscopy,...
The electrophoretic deposition process (EPD) was utilized to produce bioactive hydroxyapatite/chitosan (HAP/CS) and hydroxyapatite/chitosan/gentamicin (HAP/CS/Gent) coatings on titanium. bioactivity of newly synthesized composite investigated in the simulated body fluid (SBF) examined by X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy. obtained results revealed carbonate-substituted hydroxyapatite after immersion SBF, emphasizing...
This paper describes a promising electrophoretic deposition (EPD) approach for developing composite coatings based on chitosan with the additional components of hydroxyapatite, graphene, and gentamicin titanium substrate. Bioactive properties were investigated in vitro by immersing simulated body fluid (SBF) at 37 °C. The newly formed biomimetic layer top deposited chitosan-based Ti was confirmed X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron...
Calcium phosphate coatings were electrochemically deposited on titanium from the aqueous solution of Ca(NO3)2 and NH4H2PO4 with current density 10 mA cm-2 for deposition time 15 min. The obtained brushite coatings, (CaHPO4?2H2O), converted to hydroxyapatite (HA) by soaking in simulated body fluid (SBF) 2, 7 14 days. characterized X-ray diffraction (XRD), scanning electron microscopy (SEM) atomic force (AFM). It was shown that increase increases porosity, roughness crystallite domain size HA...
The objective of this study was the review natural zeolite, modified with acid, as a candidate material for remediation groundwater contaminated by uranium(VI). zeolite samples were obtained treatment - clinoptilolite acids: hydrochloric, oxalyc and citric. Starting zeolites characterized chemical analysis, SEM, XRPD IR spectroscopy, thermal (TG/DT) analysis determination cation exchange capacity, while starting nonadsorbed amounts uranium(VI) ion determined fluorometric method. Batch...
Increasing need for improved, compatible bone tissue implants led to the intensive research of novel biomaterials, especially hydroxyapatite (HAP)- -based composite materials on titanium and alloy surfaces. Owing its excellent biocompatibility osteoinductivity properties, is often used as part biomaterials aimed orthopedic implant applications. In order overcome persistent problems bacterial infection, various antimicrobial agents their incorporation in such medical devices were...
An aqueous boehmite sol was prepared by the peptization of Al(OH)3. The electrophoretic deposition coatings on titanium from performed at a constant voltage (from 1.0 to 10 V) and for time 30 min). Increasing applied increased mass coating. It shown that maximum thickness, low porosity good adhesion can be formed lower voltages longer times. powder, obtained drying sol, were thermally treated 1000 ?C 1300 with holding period 1 h temperature. X-Ray diffraction analysis samples confirmed...
This study presents comparison of our recently formulated two compartmental model with General fractional derivative (GFD) and Korsmeyer?Peppas, Makoid?Banakar Kopcha diffusion models. We have used GFD to the release gentamicin in poly (vinyl alcohol)/chitosan/gentamicin (PVA/CHI/Gent) hydrogel aimed for wound dressing medical treatment deep chronical wounds. The PVA/CHI/Gent was prepared by physical cross linking poly(vinyl alcohol)/chitosan dispersion using freezing-thawing method, then...
The ethical dilemmas of using animals as in vivo models preclinical and clinical examinations have been increasingly present recent decades. Small laboratory (rats, rabbits) will continue to be used because they are cost-effective permit the formation statistically testable cohort groups; a task that, for financial, maintenance care reasons, is almost prohibitive larger animals. Technological advances production new biomaterials use enormous, but screening tests methods assess...
In this work, the dissolution behavior of a polyphosphate glass, with composition 45P2O5?3SiO2?25K2O?15CaO?10MgO?ZnO?MnO (mol %), in simulated body fluid (SBF) at temperature 37 ?C for different times was studied. Two powder sizes glass (granulation: 0.1?0.3 and 0.3?0.65 mm) bulk were investigated. The experiments conducted under stationary conditions. Changes normalized mass release, concentration ions, pH values, surface morphology determined as function time. initial rates leaching well...
Biocomposite hydroxyapatite/poly(vinyl alcohol)/chitosan/gentamicin coatings were fabricated on titanium by electrophoretic deposition process (EPD) from an aqueous suspension using the constant voltage method. Characterization of deposited was performed scanning electron microscopy with field emission (FE–SEM), Fourier transform infrared spectroscopy (FT–IR) and X-ray diffraction (XRD) after immersion in simulated body fluid (SBF) at 37 °C. The concentration released gentamicin determined a...
