Nanostructured metallic surfaces support surface plasmon (SP) excitations. The resonance conditions depend on the optical properties at the metal-dielectric interface. For instance, the monitoring of the shift of the surface plasmon resonance (SPR) due to molecular adsorption events is a well-established approach in biosensing. The SPR condition also leads to an increase in the electric field...

We have built and investigated the properties of a nanofluidic Helmoltz resonator operating with superfluid $^4$He. The density oscillations of the fluid are measured with an on-chip capacitor, allowing us to probe a small volume of helium contained in the resonator. Oscillators based on superfluid $^4$He are expected to reach high quality factors due to its high purity and dissipationless...

Magnetic properties for isolated and small-scale assemblies of nanoparticles are generally derived from measurements of bulk nanoparticle systems. To complement this, we aim to investigate these properties for individual assemblies of single-domain magnetite nanoparticles.
Nanoparticles, ~ 50 nm in size and harvested from magnetotactic bacteria, were deposited by Nano eNnabler (BioForce...

When a short pulse of laser light is focused to a small spot, the energy density may be high enough to ablate and partially ionize whatever material was in the focal volume of the laser (whether it was a solid, liquid, or gas.) This ionized gas plume can strongly interact with the incident laser pulse, quickly leading to significant heating and further ionizations, resulting in a...
