Gold as a dopant in selenium-containing carbonated hydroxyapatite fillers of nanofibrous ε-polycaprolactone scaffolds for tissue engineering

Nanofibrous ε-polycaprolactone scaffolds containing Ag-doped magnetite nanoparticles: Physicochemical characterization and biological testing for wound dressing applications in vitro and in vivo

“…These distortions create large amounts of defects in the crystals, including those located on the surface (steps, kinks, ad atoms, etc.). These surface defects do not only present a source of roughness per se , but they also cause the further misalignment in the packing of the neighboring grains, which increases the inter-granular porosity and thus, the surface roughness [ 80 , 81 ]. Because of the higher surface energy associated with rougher surfaces, such material structures tend to display a higher chemical activity, in part because these defects can act as ionic traps in the host environment.…”

RETRACTION NOTICE: Mechanical, microstructural properties and cell adhesion of Sr/Se-hydroxyapatite/graphene/polycaprolactone nanofibers

“…The optimized mechanical properties of bone could be assigned to its hierarchical structures. [11][12][13][14] The collagen fibers display a triple-helical configuration/design which exhibits the high tensile strength concomitant with flexibility while HAP enhances the compressive strength, the bone-bonding, and the osteoconductivity. [15][16][17] Moreover, the natural HAP differs from the synthetic one; the former contains multi-dopants of trace elements.…”

Advances in the application of gold nanoparticles in bone tissue engineering

“…Goldcontaining bioactive glasses is a solid-state synthesis to produce alternative biomaterials for bone implantation. Electrospinning materials have high tensile strength, adjustable porosity and excellent electrophysiological performance [67,68]. 3D printing materials can refine the implant and enhance the information exchange with cells [69].…”
