Summary: While pure titanium is already a popular choice for medical applications due to its mechanical and chemical properties, this study explores how surface texturing can further enhance its functionalities. The researchers used picosecond pulsed laser ablation to create precise mesh-type surface textures on pure titanium, resulting in improved wettability and biocompatibility. Evaluation tests showed that the mesh-type surface textures had a positive effect on the biocompatibility of BMSC cells due to enhanced hydrophilicity.

Summary: Developing antimicrobial surfaces, including antimicrobial peptide coatings, is a promising approach to overcome dental implant-associated infection. This study presents a fast and efficient chemoselective conjugation technique to coat titanium implant surfaces with antimicrobial peptides. The evaluated surfaces showed antibacterial potency against primary colonizers and pathogens of dental surfaces, as well as demonstrated long-term viability of human dental pulp stem cells.

Summary: The study found that picosecond Nd:YAG laser irradiation caused chemical and morphological changes on the surfaces of commercially pure titanium and Ti-13Nb-13Zr alloy, including morphological alterations, microcracks, hydrodynamic structures, and titanium oxide formation. The increased energy absorption in the irradiation-affected area led to an increase in damaged area dimensions and surface roughness.

Summary: The biological properties of anodized titanium implants decorated with MnO nanoparticles were studied. The effects of anodic oxidation voltage on the microstructure of titanium oxide nanotubes were investigated. MnO nanoparticles were synthesized and their size and morphology were studied. The synthesized MnO nanoparticles were then decorated onto the anodized titanium implants and their biocompatibility was evaluated.

Summary: Surface textures with different orientations on Ti-6Al-4V alloys affect fretting wear behavior, leading to variations in COF curves and system deformation. Groove spacing influences wear debris formation and movement during fretting tests, providing potential for new tribology design for fretting friction pairs.

Summary: The surface topography of Ti6Al4V biomedical implants was modified using pulse laser surface melting (pLSM) to enhance fibroblast cell attachment, resulting in significantly improved cell attachment compared to control surfaces. Surface with a 10 μs pulse duration and 75% hatch spacing showed the most enhanced cell attachment due to the induced feature size comparable to cell size, and the periodic textures resulted in a homogeneous distribution of cells.

Summary: This study investigates the influence of laser-textured titanium alloy surface properties on stem cell adhesion and proliferation, demonstrating that different texture structures and chemical treatments can affect cell activity and proliferation. Laser treatment promotes the conversion of Ti and Ti2O3 to TiO2, and elements at the bottom of grooves migrate along the groove edges.

Summary: This paper discusses the corrosion behavior of Titanium Grade 2 after non-contact laser functionalization using Direct Laser Interference Lithography (DLIL). The results show that laser-textured surfaces improve titanium corrosion resistance in physiological saline, with a more stable passive layer. The enhanced corrosion resistance in DLIL samples is mainly attributed to changes in surface topography, chemical composition, and oxide film thickness.
