Among metals, Ti and majority of its alloys exhibit excellent biocompatibility or tissue compatibility. Although their high corrosion resistance is a factor in the alloys, it clear that other factors exist. In this review, passive film are compared to those metallic biomaterials, band gap energies, Egs, discuss role Eg reactivity with living tissues. From perspective material's surface, possible explain by considering following factors: ions immediately stabilized not show toxicity if released body fluids; good balance positive negative charges dissociation surface hydroxyl groups on film; low electrostatic force inducing natural adsorption proteins maintaining conformation; strong property as n-type semiconductor; lower energy generating optimal reactivity; calcium phosphate formation caused reactivity. The results suggest due oxide film, between appropriate predominate solution for Ti.

Abstract Surface decoration of living cells by exogenous substances offers a unique tool for understanding and tuning cell behaviors, which plays critical role in cell‐based therapy. Here, facile yet versatile approach decorating individual with multimodal coatings is reported. By simply co‐depositing dopamine under cytocompatible condition, various functional small molecules polymers can be encoded to form multifunctional coating on cell's surface. The accessibility versatility this method decorate diverse cells, including bacteria, fungi, mammalian demonstrated. With the ability tune surface functions, ligand co‐deposited gut microbiota prepared as oral therapeutics targeted treatment colitis. Given dual cytoprotective targeting effects coating, decorated show more than 30‐times higher bioavailability fourfold accumulation inflamed tissue comparison those uncoated bacteria. Multimodal therapeutic further validate strikingly increased efficacy over clinical aminosalicylic acid colitis mice. Decorating proposes robust platform developing enhanced

Depending on the requirements of specific applications, implanted materials including metals, ceramics, and polymers have been used in various disciplines medicine. Titanium its alloys as implant play a critical role orthopedic dental procedures. However, they still require utilization surface modification technologies to not only achieve robust osteointegration but also increase antibacterial properties, which can avoid implant-related infections. This paper aims provide summary latest advances techniques, titanium alloys, specifically biomedical applications. These techniques include plasma spray, physical vapor deposition, sol-gel, micro-arc oxidation, etc. Moreover, microstructure evolution is comprehensively discussed, followed by enhanced mechanical osseointegration, clinical outcomes. Future researches should focus combination multiple methods or improving structure composition composite coating further enhance performance.

Surface treatment modification to improve tissue bonding inhibit bacterial adhesion are considered in this review. The mechanical titanium superior those zirconia; some studies have shown that can be used a dental implant, especially abutment. Extensive surface research is ongoing osseointegration soft phenomena which make it difficult evaluate materials themselves without treatment.
