The brightest and most vivid colours in nature arise from the interaction of light with surfaces
that exhibit periodic structure on the micro- and nanoscale. In the wings of butterflies, for …

Cucurbit[n]urils (CB[n]) are macrocyclic host molecules with subnanometer dimensions
capable of binding to gold surfaces. Aggregation of gold nanoparticles with CB[n] produces a …

Palladium and platinum are important catalytic metals, and it would be highly advantageous
to be able to use surface enhanced Raman spectroscopy (SERS) to study reactive species …

Metallic nanoscale voids (“anti-nanoparticles”) are shown to possess radically different
plasmon modes to metal nanoparticles. Comparing new boundary element calculations for the …

The reliable discrimination of mutations, single nucleotide polymorphisms (SNPs), and other
differences in genomic sequence is an essential part of DNA diagnostics and forensics. It is …

Coherent anti-Stokes Raman spectroscopy (CARS) is a well-known tool in multiphoton
imaging and nonlinear spectroscopy. In this work we combine CARS with plasmonic surface …

We show how the macrocyclic host, cucurbit[8]uril (CB[8]), creates precise subnanometer
junctions between gold nanoparticles while its cavity simultaneously traps small molecules; …

The pathogenesis underlining many neurodegenerative diseases remains incompletely
understood. The lack of effective biomarkers and disease preventative medicine demands the …

Even 35 years after the discovery of surface-enhanced Raman spectroscopy (SERS) much
remains to be learned about the phenomenon. (1-3) Despite broad consensus on the …

Distinction between closely related and morphologically similar cells is difficult by conventional
methods especially without labeling. Using nuclear-targeted gold nanoparticles (AuNPs) …
