摘要：

The elaboration of silica nanobeads where gold nanoclusters are strongly adsorbed onto the surface of only one hemisphere was per-formed by (i) immobilizing a monolayer of silica nanoparticles along the air/water or onto a glass substrate and (ii) reacting with colloidal gold nanoparticles or sputtered metallic gold. The dissymetrization routes are described, analyzed and compared. (C) 2001 Elsevier Science B.V. All rights reserved.
