A THREE-DIMENSIONAL DISPERSIBLE NANORESONATOR STRUCTURE FOR BIOLOGICAL, MEDICAL AND ENVIRONMENTAL APPLICATIONS AND METHOD FOR MANUFACTURE THEREOF

摘要

A three-dimensional nanoresonator structure has a stack of laterally confined layers including at least a first layer and a second layer of different conductive materials between which a dielectric layer is interposed. The layers have at least a respective accessible surface area exposed to an environment in which the structure is immersed. Multiple three-dimensional nanoresonators that can be dispersed in an environment are formed from an array of nanoresonators fixed to a sacrificial substrate. The nanoresonators are subsequently separated from the substrate and conjugated with a chemical agent adapted to promote the formation of a stable colloidal suspension of nanoresonators in a liquid medium.

1. Three-dimensional electromagnetic nanoresonator structure, comprising a stack of laterally confined layers including at least a first layer and a second layer of a respective conductive material between which a dielectric layer is interposed, which can be represented by a resonant equivalent electrical circuit having a nominal resonant frequency determined by geometrical dimensions of the structure,
wherein said first and second layer include different conductive materials, and said layers of conductive material and said dielectric layer have at least a respective accessible surface area, adapted to be exposed in a liquid environment in which said structure is immersed.
