Abstract

We report a protocol for the direct synthesis of hexagonal silica nanostrands inside anodic alumina membranes using cationic surfactants as templates. When coated with layers of trimethylsilyl moieties, the nanostrands were a powerful tool for the ultrafine filtration of noble metal and semiconductor nanoparticles.
