The structures and antibacterial properties of nano-SiO2 supported silver/zinc–silver materials

Effects of adsorbed and templated nanosilver in mesoporous calcium-silicate nanoparticles on inhibition of bacteria colonization of dentin

“…17,18 Inorganic metal such as silver (Ag) or metal ions such as silver ion (Ag + ) or zinc ion are alternatives to antibiotics because they possess broad spectrum bactericidal effects and show no evidence of tolerance and resistance by target bacteria. 19,20 Thus, many researchers have incorporated antibacterial metal or metal ions into biomaterials, such as mesoporous bioglass or silica nanoparticles, to achieve both antibacterial and pro-osteogenic effects. 12,21,22 Two strategies have been employed for incorporating antibacterial metal or metal ions into biomaterials: adsorption and templating.…”

“…12,21,22 Two strategies have been employed for incorporating antibacterial metal or metal ions into biomaterials: adsorption and templating. 12,20,22,23 For mesoporous biomaterials, the adsorption method was most often used for loading antibacterial reagents because of its simplicity. 10,23 However, the loading amount of antibacterial metal or metal ions can be more easily controlled by the template method, and the metal or metal ions loaded by the template method are more stable in the carrier material.…”

“…Due to this porous structure SiO 2 is able to absorb ions and organic molecules quite easily, making it highly efficient and a promising carrier for antimicrobial applications. As observed in previous examples in this review, metal-containing inorganic materials has shown to be effective as antimicrobial agents; therefore a study was conducted and has implemented zinc and silver into SiO 2 nanoparticles as a means of creating a high-performance bactericidal agent [18]. In the experiment conducted by a Jia [18] they synthesized two different types of SiO 2 particles one that has been loaded with silver cations known as SLS and a co-absorption of zinc-silver loaded into the other, titled SLSZ.…”

In the experiment conducted by a Jia [18] they synthesized two different types of SiO 2 particles one that has been loaded with silver cations known as SLS and a co-absorption of zinc-silver loaded into the other, titled SLSZ. The SiO 2 particles were around 20nm ± 5nm in size and composed of 0.5 % Ag + and 4-9% of Zn 2+ in the SLZS with the amount of silver ions evenly distributed in each of both SLS and SLZS.…”

“…In this review only a handful of the metal oxides will be examined, but there are many more that have also been shown to exhibit antimicrobial properties [14][15][16][17][18].…”
