Composite Nanoparticle Structures for Chemical and Biological Sensing |
| 摘要 |
Described herein is a nanoparticle that enhances the interaction of the nanoparticle and/or a molecule/material deposited on the surface of the nanoparticle with light, comprising a pair of stacked metallic disks separated by a non-metallic spacer, wherein: (a) the dimensions of the disks and spacer are smaller than the wavelength of the light; and (b) the nanoparticle enhance the light interaction at least three times greater than that an individual metallic disk. Methods for making the nanoparticle and methods for using the nanoparticle in a variety of assays are also provided. |
