Abstract

Bioactive porous silica particle coatings were fabricated on the stainless steel substrates as bone repairing implants to enhance the apatite deposition. The particles were prepared from tetraethoxysilane (TEOS) and cetyltrimethylammonium bromide (CTAB) via the sol-gel method and then calcined at 600°C for 2 h to produce the porous structure. Subsequently, the clean substrates were sequentially soaked in the chitosan, silica and calcium alginate solutions to obtain the chitosan/silica/calcium alginate coatings via the charged layer-by-layer deposition technique. The treated substrates deposited bioactive apatite when soaked in the Kokubo's simulated body fluid (SBF) and exhibited bioactivity. Thus, such bioactive porous silica coatings are applicable to the reservoirs for storing and releasing the bone factors.
