Synthesis and Characterization of Silver-containing Sol-gel Derived Bioactive Glass Coating

The effect of applied voltages on the structure, apatite-inducing ability and antibacterial ability of micro arc oxidation coating formed on titanium surface

“…In order to improve the antibacterial ability of titanium and its alloys, some modified methods including sol-gel method [ 5 , 6 ], electrochemical deposition method [ [7] , [8] , [9] , [10] ] and micro arc oxidation method [ [10] , [11] , [12] , [13] , [14] , [15] , [16] ] are used to fabricate the coating containing antibacterial elements such as Ag, Zn and Cu elements.…”

“…According to previous studies [ [4] , [5] , [6] , [7] , [8] , [17] , [18] , [19] , [20] , [21] ], it was well known that the Ag and Cu elements possess good antibacterial ability. However, their potential cytotoxicity must be considered.…”

Sol‐gel preparation and properties of Ag‐containing bioactive glass films on titanium

“…When infection occurs, the bacteria form biofilm on the implant surface, which is difficult to be destroyed by antibacterial agents from outside. Together with copper, silver is another effective inorganic antimicrobial regent that has been added into hydroxyapatite, bioactive glass, MgO and other bioactive ceramic coatings to promote bone tissue growth and inhibit bacteria from adhering on titanium and other metallic implants. In comparison to the coating techniques of vapor deposition and thermal spray, sol‐gel coating method has the merits of good adjustment of coating composition, relatively easy processing, independence of substrate shape, etc …”

“…The Ag‐containing bioactive glass (Ag‐glass) powders were sol‐gel prepared and exhibited antibacterial activity; however, the structure and properties of sol‐gel prepared Ag‐glass coatings have rarely been studied . In this work, AgNO 3 was added into the SiO 2 ·CaO·P 2 O 5 sol, and the glass films containing different silver contents were dip coated on titanium substrate.…”

“…10,11 The Ag-containing bioactive glass (Ag-glass) powders were sol-gel prepared and exhibited antibacterial activity; [12][13][14][15] however, the structure and properties of solgel prepared Ag-glass coatings have rarely been studied. 5 In this work, AgNO 3 was added into the SiO 2 ÁCaOÁP 2 O 5 sol, and the glass films containing different silver contents were dip coated on titanium substrate. Microstructure, chemical composition, adhesion, corrosion resistance, antibacterial property, and bioactivity of the coated samples were investigated.…”
