Figure 2From: Effect of mesoporous silica under Neisseria meningitidis transformation process: environmental effects under meningococci transformation(a) SEM image of SBA-16 exhibits rounded shape with diameter size between 15 and 20 μm and of an "aggregated morphology". TEM images of SBA-16 showed well ordered cubic mesoporous which confirmed the 3D cubic pore structure, when (b) viewed along the pore axis and (c) perpendicularly to the pore axis.Back to article page
