A simple change of counteranions in catalytic templates for biomimetic silicification on surfaces dictates the size of silica nanostructures formed. It is found that the charge density of the counteranions plays an important role in controlling the structures of both templates and silica in the biomimetic silicification on surfaces (see image; scale bar = 500 nm).
