Due to the substrate morphology, and relatively small thickness of the coatings from 91 to nm , similar morphologies to that of bare alloy surface were observed overall for GNP- Fig. Samples were coated with 10 nm Au prior to imaging to obtain electrical conductivity.

The presence of SS in the coatings is assumed to be the major reason for the enhancement of cell proliferation because of its attractive bioactive properties in tissue engineering field.

However, it was surprising to achieve a similar outcome of cell differentiation experiments for bare and GNP-functionalized specimens. A pseudo-Voigt diffraction line profile was used in the fitting procedure.

Over the past few years, graphene G has received increased attention due to its unique physical and chemical properties, and its resulting biocompatibility. After washing the samples with deionized water, cells were air-dried for 24 h. Deposition of calcium phosphate by the pre-osteoblasts maintained in contact with the developed biomaterials doona demonstrated by ARS staining Fig.

Refresh and try again. The results showed that the newly developed alloy presents a very high strength, high plasticity and a low Young's modulus relative to titanium alloys currently used in medicine.

Moreover, the use of osteogenic medium could have been masking the effects promoted by GNP alone. Just a moment while we sign you in to your Goodreads account. SS, a hydrophilic, douna soluble macromolecular glycoprotein from silk worm cocoon, was proposed to be used in the composite coatings due to its demonstrated bioactivities, including cell adhesion, biodegradability, biocompatibility, and low-immunogenicity.

Coina far, investigations have been carried out to explore the use of G and GBMs for drug delivery, 13—16 biological sensing and imaging, 17—21 and as antibacterial materials, 22—25 and biocompatible scaffolds for cell culture.

The strain—stress diagram of Gum-type alloy in as-obtained condition is shown in Fig.

Thus, it has been explored in the neuronal regeneration, 43,44 skin regeneration, 45 myocardial repair, 46 SS capped particles 47,48 and even fabrication of self-assembled nanoparticles for cancer treatment.

The authors outlined that the strong noncovalent binding abilities of G allow it to act as a preconcentration platform for osteogenic inducers, which accelerate MSCs commitment toward the osteogenic lineage. Subsequently, the samples surfaces were grinded down to grit SiC paper Buehler CarbiMet in order to remove any surface defects induced by cutting.

The XRD spectra corresponding ad the as-obtained alloy are shown in Fig. This will prevent Doina from sending you messages, friend request or from viewing your profile.

Due to the substrate morphology, and relatively small thickness of the coatings from 91 to nmsimilar morphologies to that of bare alloy surface were observed overall for GNP- Fig. This finding indicates that all modified alloy surfaces stimulate cell proliferation, although to a different extent, namely with the SS- and GNP—SS-coated substrates having a much more prominent impact on cell proliferation than the GNP-coated surface.

Moreover, the OD values corresponding to ALP activity exhibited by MC3T3-cells grown on the GNP and bare alloy substrates did not show any significant difference, suggesting that GNP coating had no effect on the potential of the Gum alloy to induce the early stages of osteoblast differentiation.

These results strengthen the findings of ALP assay and mineral quantification.
