Focusing of Surface Plasmon Wave for Small‐Molecule Sensing
Miniaturized manipulation and control of surface plasmon waves have long been a desirable goal. However, conventional nanomethods have high losses and uncontrollable outcomes, which limit their utility in light–matter interaction. To overcome these challenges, a method for achieving directional prop...

description | Miniaturized manipulation and control of surface plasmon waves have long been a desirable goal. However, conventional nanomethods have high losses and uncontrollable outcomes, which limit their utility in light–matter interaction. To overcome these challenges, a method for achieving directional propagation and concentration of surface plasmon waves using nanostructures is proposed. By focusing the transmission of surface plasmon waves on the tip of a nanotriangle, the power of light is enhanced by an order of magnitude. This design can be applied to sensing small molecules, both living and nonliving. It is believed that this approach can be used to realize real‐time, integrated biosensing on miniaturized chips. |
