Antibacterial Properties and Biocompatibility of Multicomponent Titanium Oxides: A Review

Area of Science:

• Materials Science
• Biotechnology
• Nanotechnology

Background:

• Simple metal oxides (titania, zirconia, ZnO) exhibit known antibacterial and biocompatible properties.
• These oxides are utilized in air/water filtration, food packaging, and medical implants.
• Expanding applications requires exploring composite multicomponent oxides with diverse metallic ions.

Purpose of the Study:

• To review synthesis methods for multicomponent oxides.
• To discuss in vitro and in vivo testing for antimicrobial and biocompatibility assessments.
• To explore mechanisms and future applications of these advanced materials.

Main Methods:

• Wet chemical conversion, oxide nanopowder manufacturing, and mechanosynthesis.
• In vitro testing using bacterial (e.g., Escherichia coli, Staphylococcus aureus) and fungal cultures.
• Cytotoxicity and cell adhesion/proliferation/differentiation studies using cell lines (e.g., MSCs, MG63, SaOS-2).

Main Results:

• Multicomponent oxides offer diverse morphologies (thin films, multilayers, scaffolds).
• In vitro tests provide initial data on antimicrobial and cytotoxic effects.
• In vivo tests are crucial for evaluating real-world applicability.

Conclusions:

• Multicomponent oxides present expanded potential for antimicrobial and biocompatible applications.
• Understanding synthesis, morphology, and testing is key to material development.
• Future research should focus on novel applications and refining material properties.
