Dip coated silicon-substituted hydroxyapatite films

Nanostructured Si, Mg, CO3 2− Substituted Hydroxyapatite Coatings Deposited by Liquid Precursor Plasma Spraying: Synthesis and Characterization

“…The synthesized coatings had final compositions the same as the starting compositions, suggesting full incorporation and uniform distribution of the trace elements into the HA structure. The process also saves further heat treatment steps generally required in other preparation techniques such as sol-gel and co-sputtering ( Ref 6,10,22,24,25). Overall, our results have demonstrated that the LPPS process is an effective and simple method to synthesize trace element substituted HA coatings.…”

Fabrication of novel Si-doped hydroxyapatite/gelatine scaffolds by rapid prototyping for drug delivery and bone regeneration

“…Gelatine is a biocompatible product coming from the degradation of collagen, majority phase in bone, and HASi is among the most interesting bioceramics from the bioactivity point of view. In vitro experiments, in powdered form as well as coatings have evidenced an important improvement of the bioactive behavior with respect to nonsubstituted apatites [10][11][12]This means that HASi will bind faster to the bone after implantation, ensuring the osteointegration. Furthermore, an in vivo study, comparing the rates of bone apposition to HA and HASi ceramic implants demonstrated bone apposition to be significantly greater at the surface of HASi implants [13,14].…”

The role of surface wettability and surface charge of electrosprayed nanoapatites on the behaviour of osteoblasts

“…A number of techniques for the deposition of thin coatings have been investigated over recent years, and these include sputtering [10][11][12], electrospraying [13,14], pulsed laser deposition [15,16] and the sol-gel method [17,18]. Electrospraying appears to be a promising technique to deposit nanoapatites onto implant surfaces.…”
