Single Molecule SERS in a Single Gold Nanoparticle-driven Thermoplasmonic Tweezer

Sunny Tiwari, Utkarsh Khandelwal, Vandana Sharma +1

Surface enhanced Raman scattering (SERS) is optically sensitive and chemically specific to detect single molecule spectroscopic signatures. Facilitating this capability in opticall…

Beaming Elastic and SERS Emission from Bent-Plasmonic Nanowire on a Mirror Cavity

Sunny Tiwari, Adarsh B. Vasista, Diptabrata Paul +2

We report on the experimental observation of beaming elastic and surface enhanced Raman scattering (SERS) emission from a bent-nanowire on a mirror (B-NWoM) cavity. The system was…
