“…One way to improve the biocompatibility of an implant material is to modify its surface in an appropriate manner, e.g., by grinding; by polishing [ 4 , 5 ]; with the use of various oxidative treatments, such as acid and alkaline etching [ 6 , 7 ]; anodic and thermal oxidation [ 6 , 8 , 9 ]; and coating with a bioactive, chemically stable, and mechanically resistant film [ 1 ]. Mordenite Framework Inverted (MFI) zeolite films are candidates for use as a film for this purpose [ 10 , 11 , 12 ].…”

We investigated the use of a supported silicalite-1 film (SF) as a promising coating for metallic materials used in the fabrication of prostheses. The role of carbonaceous residua present on high-temperature calcined-SF in generating singlet oxygen for future use as a sterilization method has also been addressed, and the potential genotoxicity of these residua in osteoblast-like cells has been investigated. Calcination of as-synthesized SF induced the appearance of a rather complicated mixture of aliphatic and aromatic species on its outer surface. A series of variously volatile polycyclic aromatic hydrocarbons (PAH), including naphthalene, fluorene, phenanthrene, anthracene, fluoranthene, and pyrene, were identified in micromole concentrations. Irradiation of these PAHs on calcined-SF immersed in air-saturated chloroform led to the formation of very low concentrations of singlet oxygen. However, an increased level of DNA damage was observed on calcined-SF by immunofluorescence staining of phosphorylated histone H2AX analyzed by flow cytometry.

“…Ti-6Al-4V is used because of both its biocompatibility properties [39] and MRI compatibility [10] making it possible to address medical application fields. Due to its cold-welding propensity [40], Ti-6Al-4V parts are first milled and then chemically coated [41].…”

“…Hydrophilic surfaces seem to favor the interactions with biological fluids and cells when compared to the hydrophobic ones [7] [8], and hydrophilicity is affected by the surface chemical composition. Titanium and titanium alloys are frequently exploited as implant materials, because of their anticorrosive properties, mechanical properties, lightness and excellent biocompatibility of their surface oxides [9]. However, titanium is a bioinert material, i.e., the interface between titanium and host bone consists of simple interlocking attachment, without physic-chemical bonding with bone [10] [11].…”

In this study a modified Kokubo's treatment (MKT) was used to bioactivate titanium implants. Titanium surfaces were alumina-blasted and etched in HCl/H 2 SO 4 solution followed by treatment in autoclave at 120˚C for 1, 3, 5 hour periods with chemical solutions containing 1, 2 and 3 M of NaOH. The materials were characterized by surface angle measurements, roughness, field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), and in vivo tests. Statistical analysis by polynomial regression showed that solutions within 2.2 and 2.8 M NaOH lead to surface contact angles close to zero degree after 1 h of treatment. XPS analysis carried out on a sample treated 1 h in 2.2 M NaOH indicated the presence of a titanate film. This solution was selected to treat titanium implants for in vivo tests. These tests were performed on sheep in three types of separating surfaces: machined group (standard), SLA group (A) and MKT group (B) divided into two time intervals of 3 and 6 weeks. The samples in group B displayed better results compared to group A only after 6 weeks in terms of counter torque and bone implant contact (BIC).
