Summary: PVDF is an advanced functional polymer with excellent properties, and this study proposes a new strategy for the fabrication of nanocomposites by combining PVDF with advanced inorganic nanomaterials. Through electrophoretic deposition, films containing PVDF and nanoparticles like TiO2, MnO2, and NiFe2O4 can be fabricated, with the use of caffeic acid and catechol violet as co-dispersants found to aid particle dispersion, charging, and deposition.

Summary: Titanium dioxide-silica composite nanoparticles were synthesized using a verified Stober sol-gel method. The resulting nanoparticles consisted of titanium dioxide cores surrounded by ultrafine silica particles, forming a thin shell. These nanoparticles were deposited on a stainless steel substrate via electrophoretic deposition to enhance its biological response. The presence of a silica shell increased the surface roughness, eliminated cracks, and improved the adhesion and barrier performance of the coating.

Summary: The electrophoretic deposition (EPD) of gentamicin and chitosan in Titanium (Ti) nanotubes was performed to establish a local, prolonged antibiotic delivery system for periprosthetic joint infection (PJI) prevention. The results showed that EPD allowed a higher amount of gentamicin deposition compared to the air-dry method. The cross-linked chitosan layer enabled diffusion-driven release kinetics for up to 3 days. Gentamicin-loaded Ti nanotubes effectively inhibited bacterial growth and had no significant effect on osteoblast viability.

Summary: Titanium diboride-chitosan composite coatings were successfully produced by electrophoretic deposition techniques. The effect of process parameters on the coatings was investigated and the suspension properties and deposition mechanism were discussed. The results showed that the coatings had a uniform and crack-free morphology, and the chitosan content significantly affected the adhesion behavior.

Summary: The fabrication of micro-nano-structured Ti substrates using double acid corrosion and hydrothermal treatment, followed by immobilization of mesoporous polydopamine nanoparticles as photothermal agent, resulted in physical stress on bacteria and enhanced mesenchymal stem cell osteogenic differentiation. In vivo animal experiments confirmed that the modified Ti implants could improve osseointegration.

Summary: In this study, graphene oxide was coated onto titanium using electrophoretic deposition to enhance its bioactivity. The graphene oxide-coated titanium improved cell adhesion and proliferation of astrocytes and upregulated the expression of anti-inflammatory cytokines and neuroprotective factors. These findings suggest that the graphene oxide-coated titanium has the potential to induce neuroprotective effects by regulating cell activity.

Summary: In this study, zein coatings were successfully obtained on titanium substrates by electrophoretic deposition, with the coating morphology being significantly influenced by the zein content, water to ethanol ratio, process voltage, and time. Chemical treatment of the Ti substrate surface prior to deposition was found to enhance the adhesion of the coatings. Coated titanium substrates exhibited slightly lower electrochemical corrosion resistance in aqueous solution compared to uncoated substrates, and showed well-developed surface topography and hydrophilic nature.

Summary: In this study, Sn-doped titanium dioxide was synthesized by sol-hydrothermal method, and Cu2O and Cu were deposited on its surface by photochemical reduction method to prepare a composite photocatalyst Cu2O/Cu/T60S1. The introduction of Cu2O and Cu significantly improved the photocatalytic activity of T60S1 in the degradation of organic pesticides and TC-HCl under visible light.

Summary: This study evaluates the effects of exogenous BMP-7 on the differentiation of osteoblastic cells on a nanotextured Ti surface. The results show that the concentration of BMP-7 can alter the differentiation of osteoblastic cells on different surfaces. However, on the nanotextured Ti surface, the effects of BMP-7 are limited and do not significantly increase the mineralized matrix production by differentiated osteoblasts.
