| Abstract |
A nanoantenna, upon absorbing incident light, emits focused electric and thermal fields. Our proposed 'eagle-beak' nanoantenna generates strongly amplified electric fields (hot-spots) at its tip and along its edges. Also it is designed to utilize the two field gradients for preconcentration of target molecules around the hot-spots. Previously we demonstrated non-blinking single-molecule SERS with conventional Raman molecules with excellent enhancement factor of 10^14. Here, we expand its applications to Raman polarization studies as well as biomolecular detection (i.e. amyloid beta protein). Based on the examples, well-designed eagle-beak nanoantenna can provide clues to understand physcis of surface-enhanced Raman scattering, and expand its applications to various molecular sensing mechanism. |
