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…
Optothermal pulling, trapping, and assembly of colloids using nanowire plasmons
Vandana Sharma, Sunny Tiwari, Diptabrata Paul +3
Optical excitation of colloids can be harnessed to realize soft matter systems that are out of equilibrium. In this paper, we present our experimental studies on the dynamics of si…
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…
