Metaparticles: Dressing nano-objects with a hyperbolic coating (2018)
Journal Article
Wang, P., Krasavin, A. V., Viscomi, F. N., Adawi, A. M., Bouillard, J. G., Zhang, L., …Zayats, A. V. (2018). Metaparticles: Dressing nano-objects with a hyperbolic coating. Laser and Photonics Reviews, 12(11), 1800179. https://doi.org/10.1002/lpor.201800179

The ability to engineer the optical response of a plasmonic nano‐object is highly desired to achieve better control over light–matter interactions. Due to the sensitivity of plasmon resonances to the surrounding media, isotropic dielectric coating is... Read More about Metaparticles: Dressing nano-objects with a hyperbolic coating.

Determining molecular orientation via single molecule SERS in a plasmonic nano-gap (2017)
Journal Article
Marshall, A. R. L., Stokes, J., Viscomi, F. N., Proctor, J. E., Gierschner, J., Bouillard, J. G., & Adawi, A. M. (2017). Determining molecular orientation via single molecule SERS in a plasmonic nano-gap. Nanoscale, 9(44), 17415-17421. https://doi.org/10.1039/C7NR05107G

In this work, plasmonic nano-gaps consisting of a silver nanoparticle coupled to an extended silver film have been fully optimized for single molecule Surface-Enhanced Raman Scattering (SERS) spectroscopy. The SERS signal was found to be strongly dep... Read More about Determining molecular orientation via single molecule SERS in a plasmonic nano-gap.

Dual-modal SERS/fluorescence AuNP probe for mitochondrial imaging (2017)
Journal Article
Eling, C. J., Price, T. W., Marshall, A. R. L., Narda Viscomi, F., Robinson, P., Firth, G., …Stasiuk, G. J. (2017). Dual-modal SERS/fluorescence AuNP probe for mitochondrial imaging. ChemPlusChem, 82(5), 674-680. https://doi.org/10.1002/cplu.201600593

A novel SERS/fluorescent multimodal imaging probe for mitochondria has been synthesised using 12 nm diameter gold nanoparticles (AuNP) surface functionalised with a rhodamine thiol derivative ligand. The normal pH dependant acidic fluorescence of the... Read More about Dual-modal SERS/fluorescence AuNP probe for mitochondrial imaging.
