Abundant applications of silica nanoparticles (SiNPs) have motivated many research groups for silica nanoparticles synthesis with tuned properties. Here we show the formation of SiNPs using the topdown method in a wet attrition mill with effective use of surfactants sodium laurylsulfate (SLS) and Tween80. The attrition milling was facilitated by using zirconium beads as milling media. The ...
