Dielectric metasurfaces for surface enhanced raman spectroscopy and optical trapping
In this paper, dielectric metasurfaces are proposed as engineered substrates for Surface Enhanced Raman Spectroscopy (SERS), for the detection of small biological particles, such as proteins or viruses. The advantages offered by these structures, with respect to conventional plasmonic surfaces, are discussed and the expected Enhancement Factor (EF) is derived. The exploitation of optical trapping for operation in solution is also discussed.
