Sodium alginate/gelatin with silica nanoparticles a novel hydrogel for 3D printing

3D printable SiO2 nanoparticle ink for patient specific bone regeneration

“…For this purpose, 2.5% (w/v) of sodium alginate was mixed with different concentrations of SiO 2 nanoparticles dispersed in water followed by stirring at room temperature until a homogeneous solution was obtained. 8% (w/v) of gelatin was added to the above solution under continuous stirring at 60 °C for 1 h. 20 The compositions of SiO 2 nanoparticles, sodium alginate and gelatin were listed in Table 1 .…”
