3D-TAPERED NANOCAVITIES WITH ON-CHIP OPTICAL AND MOLECULAR CONCENTRATION FOR SINGLE MOLECULE DIAGNOSTICS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18075302 titled '3D-TAPERED NANOCAVITIES WITH ON-CHIP OPTICAL AND MOLECULAR CONCENTRATION FOR SINGLE MOLECULE DIAGNOSTICS

Simplified Explanation

The plasmonic device described in the patent application consists of a support layer, an insulating layer, and a plasmonic layer that together define a cavity with a three-dimensionally tapered structure. This cavity is designed to propagate an electromagnetic field along one direction and concentrate the field at the tip of the cavity. The device also includes an opening at the tip of the cavity, allowing target molecules from a solution on the plasmonic layer to pass through.

• Support layer, insulating layer, and plasmonic layer work together to create a cavity with a tapered structure.
• Cavity propagates an electromagnetic field and concentrates it at the tip.
• Opening at the tip allows target molecules to pass through.
