Ag@SiO₂ and rhodamine-doped Ag@SiO₂ nanocomposites were prepared.Rhodamine fluorescence intensity was enhanced by a factor of 4.7 due to metal-enhanced fluorescence.The Ag core was easily oxidized by H₂O₂,enhancing the fluorescence release of rhodamine.Glucose oxidase was immobilized on the layer of SiO₂ shell by chemical cross linked cluster.A novel method to detect glucose was developed based on metal-enhanced fluorescence in a concentration range of 0.2～6.8 mmol/L with a detection limit of 0.06 mmol/L.Speedy detection response was obtained upon the fast oxidation of Ag core by H₂O₂.
