Probing light–matter interaction at the nanometer scale is one of the most fascinating topics
of modern optics. Its importance is underlined by the large span of fields in which such …

High refractive index dielectric nanoantennas strongly modify the decay rate via the Purcell
effect through the design of radiative channels. Due to their dielectric nature, the field is …

Interferometric imaging is an emerging technique for particle tracking and mass photometry.
Mass or position are estimated from weak signals, coherently scattered from nanoparticles …

Fluorescence lifetime imaging (FLI) has been receiving increased attention in recent years
as a powerful diagnostic technique in biological and medical research. However, existing …

Autofluorescence lifetime imaging microscopy (FLIM) is sensitive to metabolic changes in
single cells based on changes in the protein‐binding activities of the metabolic co‐enzymes …

Single-molecule localization microscopy is a powerful technique with vast potential to study
light–matter interactions at the nanoscale. Nanostructured environments can modify the …

We study the fundamental limit on the localization precision for a subwavelength scatterer
embedded in a strongly scattering environment, using the external degrees of freedom …

Biological membrane potentials, or voltages, are a central facet of cellular life. Optical
methods to visualize cellular membrane voltages with fluorescent indicators are an attractive …

Optical near fields are at the heart of various applications in sensing and imaging. We
investigate dipole scattering as a parameter estimation problem and show that optical near …
