Single walled carbon nanotubes reinforced mineralized hydroxyapatite composite coatings on titanium for improved biocompatible implant applications

Abstract

Carbon nanotubes reinforced mineralized hydroxyapatite (CNT/M-HAP) composite coating on titanium by pulsed electrodeposition is a promising approach to produce bioimplants with better osseointegration capacity and improved mechanical property.

Surface Treatments and Functional Coatings for Biocompatibility Improvement and Bacterial Adhesion Reduction in Dental Implantology

“…Mineral substituted hydroxyapatite and carbon nanotube reinforced mineralized hydroxyapatite composite coatings on titanium were prepared by pulsed electrodeposition. An improved viability of osteoblasts was observed in vitro on the latter coating, which was also evaluated in vivo in Wistar rats [110]. Using a compound surface treatment of sand blasting and acid etching followed by hydroxyapatite radio frequency sputtering, Lai et al assessed the feasibility of a possibly scalable process.…”

Surface Properties of Graphene Functionalized TiO2/nHA Hybrid Coatings Made on Ti6Al7Nb Alloys via Plasma Electrolytic Oxidation (PEO)

“…Therefore, comparisons of refs. [ 24 , 35 , 36 , 37 , 40 , 46 , 47 , 48 , 49 , 50 ] have been identified by a mixed review of GNS-doped hydroxyapatite coatings and surface coatings made with PEO.…”

Synthesis and characterization of β-cyclodextrin/carboxymethyl chitosan/hydroxyapatite fused with date seed extract nanocomposite scaffolds for regenerative bone tissue engineering

“…In order to cope with these limitations, Carboxymethyl chitosan 10 (CMC), is a well warranted chitosan-derived polymer, derived from carboxylation reaction of amine group substitution by smaller alkyl groups, has engrossed great interest in a wide spectrum of biomedical applications being biocompatible, cost effective and owing suitable degradation rate. In addition, CMC is better soluble in water in comparison to chitosan without the aid of acid substance, averting the damage in pH sensitive antibacterial activity of a drug [11][12] . At this juncture, it is relevant to mention that combining Chitosan derivatives with other naturally derived moieties may result in the development of a nanocomposite scaffolds with the advantages of enhanced performances in terms of solubilization and permeability.…”
