Abstract

(Figure Presented) Biofunctionalized ceramic nanowires: A reactive ester polymer has been used to immobilize silicatein, a hydrolytic enzyme involved in the biomineralization of SiO₂, on the surface of TiO₂ nanowires. The surface-bound protein retains its original hydrolytic properties and also acts as a reductant for AuCl₄^- in the synthesis of hybrid TiO₂/silicatein/Au nanocomposites.
