Journal ArticleDOI
Plasmofluidic single-molecule surface-enhanced Raman scattering from dynamic assembly of plasmonic nanoparticles
Partha Pratim Patra,Rohit Chikkaraddy,Ravi P. N. Tripathi,Arindam Dasgupta,G. V. Pavan Kumar +4 more
TL;DR: By utilizing dual excitation of plasmons at metal-fluid interface, this work creates interacting assemblies of metal nanoparticles, which may be further harnessed in dynamic lithography of dispersed nanostructures and have implications in realizing optically addressable, plasmofluidic, single-molecule detection platforms.
Journal ArticleDOI
Single-molecule strong coupling at room temperature in plasmonic nanocavities
Rohit Chikkaraddy,Bart de Nijs,Felix Benz,Steven J. Barrow,Oren A. Scherman,Edina Rosta,Angela Demetriadou,P. Fox,Ortwin Hess,Jeremy J. Baumberg +9 more
TL;DR: Statistical analysis of vibrational spectroscopy time series and dark-field scattering spectra provides evidence of single-molecule strong coupling, opening up the exploration of complex natural processes such as photosynthesis and the possibility of manipulating chemical bonds.

Research data supporting "Single-molecule strong coupling at room temperature in plasmonic nanocavities"
Rohit Chikkaraddy,Bart de Nijs,Felix Benz,Steven J. Barrow,Oren A. Scherman,Angela Demetriadou,P. Fox,Ortwin Hess,Edina Rosta,Jeremy J. Baumberg +9 more
TL;DR: The experimental data taken in the NanoPhotonics Group at the Cavendish Laboratory (University of Cambridge) collected between 1/10/2014 to 1/02/2016 were used in this paper for single-molecule strong coupling at room temperature in plasmonic nanocavities.
Journal ArticleDOI
Single-molecule optomechanics in “picocavities”
Felix Benz,Mikolaj K. Schmidt,A. Dreismann,Rohit Chikkaraddy,Yao Zhang,Angela Demetriadou,Cloudy Carnegie,Hamid Ohadi,Bart de Nijs,Ruben Esteban,Javier Aizpurua,Jeremy J. Baumberg +11 more
TL;DR: This work found that individual atomic features inside the gap of a plasmonic nanoassembly can localize light to volumes well below 1 cubic nanometer, enabling optical experiments on the atomic scale, and sets the basis for developing nanoscale nonlinear quantum optics on the single-molecule level.
Journal ArticleDOI
Strong-coupling of WSe2 in ultra-compact plasmonic nanocavities at room temperature.
Marie-Elena Kleemann,Rohit Chikkaraddy,Evgeny M. Alexeev,Dean Kos,Cloudy Carnegie,Will Deacon,Alex de Casalis de Pury,Christoph Große,Bart de Nijs,Jan Mertens,Alexander I. Tartakovskii,Jeremy J. Baumberg +11 more
TL;DR: Kememann et al. as discussed by the authors showed that room-temperature plasmon strong coupling can be achieved in compact, robust, and easily assembled gold nano-gap resonators at room temperature.
