Generation of ultralarge Surface Enhanced Raman Spectroscopy (SERS)-active hot-spot volumes by an array of 2D nano-superlenses

Surface Enhanced Raman Spectroscopy (or SERS) has received tremendous attention in the past three decades. However, the extremely-confined probe volume (1 nm) of the plasmonic hot-spots occurring on a conventional roughened SERS-active metallic surface has limited value in macro-molecular studies. I...
