1. A particulate material comprising rough mesoporous hollow silica nanoparticles having a size from 100 nm to 3000 nm; wherein the rough mesoporous hollow silica nanoparticles comprise a mesoporous shell that has an external surface that has projections thereon; wherein the projections have lengths ranging from 5 nm to 1000 nm; and wherein the projections are strands or fibres, the projections being outgrowths spaced apart from each other and extending outwardly from the mesoporous shell of the rough mesoporous hollow silica nanoparticles.
