Structural and Physical Properties of Magnetron Co-sputtered Silver Containing Hydroxyapatite Coatings on Titanium Substrates

A Review on Ionic Substitutions in Hydroxyapatite Thin Films: Towards Complete Biomimetism

“…Another important trend that is emerging regarding ion-substituted hydroxyapatite thin films, is that of antibacterial coatings. To this regard, a wide range, and increasing amount, of literature is available about silver-doped hydroxyapatite, for which deposition by magnetron sputtering [74][75][76][77][78], PLD [79][80][81][82][83][84] and MAPLE [85] has been reported. Being the study of plasma assisted deposition of Ag-doped hydroxyapatite of more recent introduction, the majority of the studies focus on the influence of deposition parameters on the films characteristics and on the evaluation of antibacterial efficacy, while extensive, comparative in vivo studies are yet to be performed.…”

Ion-Substituted Calcium Phosphates Coatings

“…Water is considered as a major interfacial host in all living environments, and it can affect the capacity of protein adsorption [77] and cellular adhesion [78]. Therefore, to interpret the microbial behavior, this parameter must be carefully taken into consideration.…”

“…Thus, the average roughness parameter was found to have a similar value (~5 nm) for Li-0 and Li-P coatings, and a double one (~10 nm), for Li-C structures. The positive values of R ku and R sk coefficients could also be related to less available surface-active sites [78,80], and, consequently, could stay at the origin of the inhibition of microbial development on the surface of synthesized structures.…”
