“…completely clear at present. Compared with other copper molecular materials, Copper-containing NPs has higher surface area and different crystal structure, and can affect different cellular components of microbial cells through some unique mechanisms to exert better antibacterial activity (54)(55)(56)(57)(58)(59). Copper-containing NPs can dissolve faster in solutions, release more metal ions, and exert a stronger antimicrobial effect (60).…”

Copper has been used as an antimicrobial agent long time ago. Nowadays, copper-containing nanoparticles (NPs) with antimicrobial properties have been widely used in all aspects of our daily life. Copper-containing NPs may also be incorporated or coated on the surface of dental materials to inhibit oral pathogenic microorganisms. This review aims to detail copper-containing NPs’ antimicrobial mechanism, cytotoxic effect and their application in dentistry.

“…The ZIF-L@TiO 2 /fabric was placed on LB solid medium and cultured for 5 days, and the antibacterial effect was still obvious ( Figure 14 B). N, F-doped TiO 2 can also be applied to cotton fabric surfaces to make light-responsive self-cleaning clothing; N, F-doped TiO 2 also exhibits excellent surface hydrophobicity, which makes it difficult for water droplets to lubricate its surface [ 144 ] ( Figure 14 C), and Cu-doped TiO 2 can also effectively remove coffee stains [ 145 ] ( Figure 14 D).…”

Traditional antimicrobial methods, such as antibiotics and disinfectants, may cause adverse effects, such as bacterial resistance and allergic reactions. Photocatalysts based on titanium dioxide (TiO2) have shown great potential in the field of antimicrobials because of their high efficiency, lack of pollution, and lack of side effects. This paper focuses on the antimicrobial activity of TiO2 under different light sources. To improve the photocatalytic efficiency of TiO2, we can reduce electron-hole recombination and extend the photocatalytic activity to the visible light region by doping with different ions or compounds and compounding with polymers. We can also improve the surface properties of materials, increase the contact area with microorganisms, and further enhance the resistance to microorganisms. In addition, we also reviewed their main synthesis methods, related mechanisms, and main application fields to provide new ideas for the enhancement of photocatalytic microorganism performance and application popularization in the future.

In this research, Fe-doped TiO2 nanoparticles were synthesized by sol-gel technique followed by annealing at 450 oC in a vacuum. The effects of Fe-doping on the morphological, elemental, structural and optical properties of TiO2 nanoparticles have been investigated. XRD analysis was performed to examine the structural properties of synthesized pure TiO2 nanoparticles and Fe-doped TiO2 nanoparticles. Surface analysis was done using Scanning Electron Microscopy. Optical properties were determined using UV/Vis spectroscopy. Morphological analysis revealed that TiO2 nanoparticles have a spherical shape. EDX analysis confirmed the elemental composition of Fe-doped TiO2 nanoparticles. XRD patterns showed that diffraction peaks can be attributed to TiO2 with the anatase phase.
