Using the near field optical trapping effect of a dielectric metasurface to improve SERS enhancement for virus detection
Abstract In this paper, we report the effect of optical trapping on the enhancement factor for Raman spectroscopy, using a dielectric metasurface. It was found that a higher enhancement factor (up to 275%) can be obtained in a substrate immersed in water, where particles are freee to move, compared...
