1. A recyclable composition for use in treating a fouling layer present on a material surface, the composition comprising a surface-functionalised, silica-based nanobead, wherein the surface is functionalised by a first moiety, the first moiety being an active enzyme selected from Proteinase K, an aldehyde oxidoreductase, a monooxygenase, bile salt-dependent lipase, phospholipase A, phospholipase C, and a DNAse.
