Controlling Raman enhancement in particle-aperture hybrid nanostructures by interlayer spacing

Kabusure M. Kabusure, Petteri Piskunen, Jarkko J. Saarinen +2

Here we show how surface-enhanced Raman spectroscopy (SERS) features can be fine-tuned in optically active substrates made of layered materials. To demonstrate this, we used DNA-as…
