“…Importantly, intaking low selenium increases the risk of mortality, poor immune function, and cognitive decline. Selenium can penetrate bacteria cells, catalyze the oxidation of intracellular thiols, and generate the singlet oxygen, which further causes the death of bacteria 27 , 28 . Besides bacteria inhibition, selenium doped nanoparticles also show effective anti-cancer properties 29 .…”

Selenium-doped nanostructure has been considered as an attractive approach to enhance the antibacterial activity of calcium phosphate (cap) materials in diverse medical applications. in this study, the selenium-doped biphasic calcium phosphate nanoparticles (SeB-NPs) were first synthesized. Then, silver was in situ incorporated into SeB-NPs to obtain nanostructured composite nanoparticles (Ag SeB-NPs). Both SeB-NPs and Ag SeB-NPs were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), ultraviolet-visible spectroscopy (UV-Vis), X-ray photoelectron spectroscopy (XPS), and Raman spectra. The results confirmed that the SeO 3 2− was doped at the po 4 3− position and silver nanoparticles were deposited on the surface of SeB-NPs. Next, Transmission Electron Microscopy (TEM) analysis displayed that the prepared Ag SeB-NPs had a needlecluster-like morphology. CCK-8 analysis revealed SeB-NPs and Ag SeB-NPs had good cytocompatibility with osteoblasts. the antibacterial activity of the prepared Ag SeB-NPs was confirmed by using Gramnegative E. coli and Gram-positive S. aureus. The above results manifested the significance of the final Ag SeB-NPs for biomedical applications. Tissue engineering has been widely used in bone graft and dentistry due to a large number of patients require grafting resulting from congenital conditions, trauma, and tumor resection, and so on 1-3. Mineralized tissues, such as bone, tooth enamel, dentin, and cementum, are enriched with significant amounts of ionic substitutions, including sodium, potassium, and carbonate groups. These elements can affect the functionality of related tissues 4,5. Calcium phosphate (CaP) based nanoparticles, including hydroxyapatite (Ca 10 (PO 4) 6 (OH) 2 , HA), β-tricalcium phosphate (Ca 3 (PO 4) 2 , β-TCP), tetracalcium phosphate (Ca 4 (PO 4) 2 O; TTCP), biphasic calcium phosphate (BCP), and so forth, were well-known in implant surgery because of their excellent biocompatibility, biodegradability, and tunable physicochemical properties. Compared to HA or β-TCP, biphasic calcium phosphate (BCP) composed of HA and β-TCP, performed better mechanical properties, higher biological activity, and adjustable degradation rate 6-10. Bacteria attached to the implanted medical devices or scaffold can cause healthcare-associated infections, such as the formation of biofilm, which further results in local inflammation and infection. Therefore, the scaffold with excellent antibacterial properties provides an overwhelming advantage in the clinic stage 11,12. Many metal nanoparticles, such as silver (Ag), zinc oxide (ZnO), and titanium dioxide (TiO 2), performed strong antibacterial properties and low toxicity towards mammalian cells, some of these nanoparticles have been widely applied in a range of areas 13-20. Silver (Ag) is stable in the body fluids and can be used in antibacterial implants due to silver can easily binds to bacterial DNA and RNA, resulting in bacteria death 21. However, the antibacterial effect of nanoparticles was influenced...

“…Nanostructured surfaces of different materials exhibit unexpected and unprecedented bactericidal effects regarding pathogenic bacteria, which is usually related either to photochemical reaction of gaseous oxygen with composing nanocrystallites, yielding in reactive oxygen species and singlet oxygen [1][2][3][4][5], or to mechanical reaction of bacterial membranes to sharp surface nanoroughness [6][7][8]. Specifically, in the case of Si a broad variety of its nanomorph-nanospike [6], nanosheets [7] and nanoparticles (NPs) [9] were demonstrated to be bactericidal.…”

Surface-enhanced IR absorption (SEIRA) microscopy was used to reveal main chemical and physical interactions between Staphylococcus aureus bacteria and different laser-nanostructured bactericidal Si surfaces via simultaneous chemical enhancement of the corresponding IR-absorption in the intact functional chemical groups. A cleaner, less passivated surface of Si nanoripples, laser-patterned in water, exhibits much stronger enhancement of SEIRA signals compared to the bare Si wafer, the surface coating of oxidized Si nanoparticles and oxidized/carbonized Si (nano) ripples, laser-patterned in air and water. Additional very strong bands emerge in the SEIRA spectra on the clean Si nanoripples, indicating the potential chemical modifications in the bacterial membrane and nucleic acids during the bactericidal effect.

“…Because nanosilica has a unique size, it has special properties (functional properties or nonreactivity). Therefore, nanosilica forms new composite materials with graphene, polydopamine, selenium, zinc oxide, silver, and other materials that have antibacterial effects 78‐80 . These materials have achieved satisfactory results in areas such as food preservation and clothing that needs to inhibit bacteria 81‐83 .…”

As the problem of bacterial contamination continues to grow in its significance, researchers have reported many antibacterial materials that are based on inorganic compounds. Of these, materials that are based on silica and its derivatives have been widely used in engineering, medicine, and food. This paper reviews the advantages, safety issues, and applications of silica and its derivatives, as reported in recent years. The information provided highlights the preparation, application, and antimicrobial efficiency of materials that are based on silica and have different structure/size. We outline the possible antimicrobial mechanisms of silica‐based materials and the potential challenges that researchers may face. With a focus on increasing concerns regarding bacterial contamination in the food and medical industries, we have also proposed corresponding antibacterial material preparation strategies.
