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…
Large-scale optothermal assembly of colloids mediated by a gold microplate
Vandana Sharma, Diptabrata Paul, Shailendra K Chaubey +2
Light-activated colloidal assembly and swarming can act as model systems to explore non-equilibrium state of matter. In this context, creating new experimental platforms to facilit…
Dielectric microsphere coupled to a plasmonic nanowire: A self-assembled hybrid optical antenna
Sunny Tiwari, Chetna Taneja, Vandana Sharma +3
Hybrid mesoscale-structures that can combine dielectric optical resonances with plasmon-polaritons are of interest in chip-scale nano-optical communication and sensing. This experi…
