Abstract
Official abstract text for this publication.
A surface enhanced Raman spectroscopy (SERS) apparatus employs a nanorod in an indentation in a surface of a substrate. The SERS apparatus includes the nanorod having a tip at a free end opposite to an end of the nanorod that is supported by the substrate indentation. The indentation has a tapered profile and supports the nanorod at a bottom of the indentation. The free end of the nanorod extends away from the indentation bottom. The SERS apparatus further includes a Raman-active material at a surface of one or both of the nanorod and the indentation. The indentation and the nanorod facilitate one or both of production and detection of a Raman scattering signal emitted by an analyte in a vicinity of the nanorod and indentation.
First claim
Opening claim text (preview).
What is claimed is: 1. A surface enhanced Raman spectroscopy (SERS) apparatus comprising: a nanorod having a tip at a free end opposite to an end of the nanorod that is supported by a substrate; an indentation in a surface of the substrate, the indentation having a tapered profile and supporting the nanorod at a bottom of the indentation, the free end of the nanorod extending away from the indentation bottom; and a Raman-active material at a surface of both of the nanorod and…
