A device is presented comprising a multi-layer structure with a plurality of metal islands on the surface of a solid transparent substrate. The islands are coated by an ultrathin sol-gel derived silica film via self-assembled monolayer.

Device and method for optical localized plasmon sensing

A method is presented for use in fabrication of metal islands on an oxide substrate. The method comprises: depositing a selected metal on the oxide substrate by evaporation of said selected metal; and annealing a film of the selected metal on said substrate at temperatures including an annealing temperature being less than 50&#xb0; C. lower than a glass transition temperature, thereby forming the metal islands partially embedded in said substrate.

Method for fabrication of localized plasmon transducers

This invention seeks to provide methods and apparatus for analysis. Electromagnetic radiation is transmitted through a plurality of metallic islands on a transparent substrate. A resultant optical property of the plurality of metallic islands is measured. Thereafter a chemical substance is adsorbed onto the plurality of metallic islands so as to produce a chemical substance-metallic islands moiety. Electromagnetic radiation is transmitted through the chemical substance-metallic islands moiety and a resultant optical property of metallic islands in the chemical substance-metallic islands moiety is measured. The resultant optical property of the metallic islands in chemical substance-metallic islands moiety and the resultant optical property of the plurality of metallic islands are employed so as to provide at least one of a quantitative indication and a qualitative indication of at least one of: the chemical substance-metallic islands moiety, a functionality of the chemical substance-metallic islands moiety, the plurality of metallic islands, a functionality of the plurality of metallic islands, the chemical substance and a functionality of the chemical substance.
