ChemInform Abstract
Novel hollow helicoid morphologies made up of hexagonal mesoporous silica are prepared using cetyltrimethylammonium chloride as surfactant micellar template and Si(OEt)4 as Si source. The hollow helicoids have the shape of an “Archimedian screw”. Siliceous hollow helicoids with spiraling mesoscale channels may find application in separating viral or bacterial particles, in chiral catalysis of macromolecules, or in the fabrication of magnetically activated screws for micro-devices.
