Abstract
The present invention relates to a high sensitivity localized surface plasmon resonance sensor and to a sensor system using same, the sensor comprising: a first metal layer including a first metal; a second metal layer arranged parallel to the first metal layer and including a second metal; and a conductive cross-linking layer disposed between the first metal layer and the second metal layer, and made of a third metal with a corrosion response that is different than that of the first metal and of the second metal.
Claims26
A localized surface plasmon resonance sensor comprising:
- a first metal layer comprising a first metal;
- a second metal layer arranged parallel to the first metal layer and comprising a second metal;
- and
- a conductive bridge layer disposed between the first metal layer and the second metal layer and comprising a third metal with a corrosion reactivity different from that of the first metal and the second metal,
- wherein the first metal and the second metal are either one or more metal selected from a group consisting of Au, Ag and Cu or an alloy comprising the one or more metal, and the first metal is same as or different from the second metal.
A localized surface plasmon resonance sensor comprising:
- a first metal layer comprising a first metal;
- a second metal layer arranged parallel to the first metal layer and comprising a second metal;
- and
- a conductive bridge layer disposed between the first metal layer and the second metal layer and comprising a third metal with a corrosion reactivity different from that of the first metal and the second metal,
- wherein the first metal layer, the second metal layer and the conductive bridge layer together form a nanostructure.
