A hole load of spheres: Nanoporous polyelectrolyte (PE) spheres are prepared through layer-by-layer deposition of oppositely charged poly(acrylic acid) and poly(allylamine hydrochloride) onto mesoporous silica spheres (with cross-linking by heating in each step), and the subsequent removal of the silica templates by hydrofluoric acid (HF; see scheme).
