Correlative extinction and single fluorophore bleaching microscopy for ligand quantification on gold nanoparticles
Nicole Slesiona, Lukas Payne, Iestyn Pope +3
Nanoparticles (NPs) are promising therapeutic delivery agents, yet it is increasingly apparent that the number and manner of presentation of cell binding ligands on the NP can affe…
Correlative light electron microscopy using small gold nanoparticles as single probes
Iestyn Pope, Hugh Tanner, Francesco Masia +6
Correlative light electron microscopy (CLEM) requires the availability of robust probes which are visible both in light and electron microscopy. Here we demonstrate a CLEM approach…
First-order perturbation theory of eigenmodes for systems with interfaces
Zoltan Sztranyovszky, Wolfgang Langbein, Egor A. Muljarov
We present an exact first-order perturbation theory for the eigenmodes in systems with interfaces causing material discontinuities. We show that when interfaces deform, higher-orde…
Sizing individual dielectric nanoparticles with quantitative differential interference contrast microscopy
Samuel Hamilton, David Regan, Lukas Payne +2
We report a method to measure the size of single dielectric nanoparticles with high accuracy and precision using quantitative differential interference contrast (DIC) microscopy. D…
Optical resonances in graded index spheres: A resonant-state expansion study and analytic approximations
Zoltan Sztranyovszky, Wolfgang Langbein, Egor A. Muljarov
Recent improvements in the resonant-state expansion (RSE), focusing on the static mode contribution, have made it possible to treat transverse-magnetic (TM) modes of a spherically…
Simultaneous microscopic imaging of thickness and refractive index of thin layers by heterodyne interferometric reflectometry (HiRef)
Alexander Nahmad-Rohen, David Regan, Paola Borri +1
The detection of spatial or temporal variations in very thin samples has important applications in the biological sciences. For example, cellular membranes exhibit changes in lipid…
A model for the complex reflection coefficient of a collection of parallel layers
Alexander Nahmad-Rohen, Wolfgang Langbein
Reflectometry is a technique that uses the light reflected by a sample to determine properties of the sample. Interferometric reflectometry uses interference between two beams, one…
Resonant-state expansion applied to three-dimensional open optical systems: A complete set of static modes
S. V. Lobanov, W. Langbein, E. A. Muljarov
We present two alternative complete sets of static modes of a homogeneous dielectric sphere, for their use in the resonant-state expansion (RSE), a rigorous perturbative method in…
Background-free 3D nanometric localisation and sub-nm asymmetry detection of single plasmonic nanoparticles by four-wave mixing interferometry with optical vortices
George Zoriniants, Francesco Masia, Naya Giannakopoulou +2
Single nanoparticle tracking using optical microscopy is a powerful technique with many applications in biology, chemistry and material sciences. Despite significant advances, loca…
Linear wave dynamics explains observations attributed to dark-solitons in a polariton quantum fluid
P. Cilibrizzi, H. Ohadi, T. Ostatnicky +3
We investigate the propagation and scattering of polaritons in a planar GaAs microcavity in the linear regime under resonant excitation. The propagation of the coherent polariton w…
Resonant state expansion applied to planar waveguides
L. J. Armitage, M. B. Doost, W. Langbein +1
The resonant state expansion, a recently developed method in electrodynamics, is generalized here to planar open optical systems with non-normal incidence of light. The method is i…
Structure and zero-dimensional polariton spectrum of natural defects in GaAs/AlAs microcavities
Joanna M Zajac, Wolfgang Langbein
We present a correlative study of structural and optical properties of natural defects in planar semiconductor microcavities grown by molecular beam epitaxy, which are showing a lo…
Brillouin-Wigner perturbation theory in open electromagnetic systems
E. A. Muljarov, W. Langbein, R. Zimmermann
A Brillouin-Wigner perturbation theory is developed for open electromagnetic systems which are characterised by discrete resonant states with complex eigenenergies. Since these sta…
