Noordam, M.L. (author)In this thesis, we explore the interaction between multiple optical light fields. Although these light fields can interfere with each other in a vacuum, actual interaction can only occur in a medium. This interaction can be amplified in materials with nanoscale dimensions such as a monolayer of WS2 and metallic nanostructures. The shapes of...doctoral thesis 2023

Wang, X. (author), Benedictus, R. (author), Groves, R.M. (author)Strain-based structural health monitoring (SHM) relies on high performance strain sensing methods. Gold nanoparticle (NP) doped fibre optic sensors not only have the potential to increase the intensity of the backscattered signal to increase the signal to noise ratio but also have plasmon resonance peaks in the visible light range. The...journal article 2022

Wang, X. (author), Benedictus, R. (author), Groves, R.M. (author)The plasmon resonance spectral peak of a gold spherical nanoparticle (NP) will shift when the NP shape is changed from sphere to spheroid. This may be used as a novel strain detection method with gold NPs embedded in a medium of different refractive index (RI). Applying a strain to the external medium will cause a change in the shape of the...conference paper 2022

Apart from the small size of the objects, biomolecules shake, shimmer, and bounce around a tremendous amount.

Shi, X. (author), Verschueren, D.V. (author), Dekker, C. (author)Plasmon resonance biosensors provide ultimate sensitivity at the single-molecule level. This sensitivity is, however, associated with a nanometer-sized confined hotspot, and molecular transport toward the sensor relies on inefficient diffusion. Here, we combine a plasmonic nanoantenna with a solid-state nanopore and demonstrate that single...journal article 2018
