A cellular-level study of the pathophysiology is crucial for understanding the mechanisms
behind human diseases. Recent advances in quantitative phase imaging (QPI) techniques …

Due to the highly inhomogeneous distributions of refractive indexes, light propagation in
complex media such as biological tissue experiences multiple light scattering events. The …

Super-resolution microscopy techniques break the diffraction limit of conventional optical
microscopy to achieve resolutions approaching tens of nanometres. The major advantage of …

Fluorogenic probes efficiently reduce non-specific background signals, which often results in
highly improved signal-to-noise ratios. Although this implies improved resolution …

Super-resolution optical fluctuation imaging (SOFI) provides an elegant way of overcoming
the diffraction limit in all three spatial dimensions by computing higher-order cumulants of …

Single-molecule fluorescence resonance energy transfer (smFRET) is a powerful technique
for studying the conformation dynamics and interactions of individual biomolecules. In this …

Fluorescence, Phosphorescence, and Chemiluminescence cover a wide array of topics.
One can simply examine the number of topics that arise from photon induced excitation and …

Probes that exploit Förster resonance energy transfer (FRET) in their feedback mechanism
are touted for their sensitivity, robustness, and low background, and thanks to the …

Förster resonance energy transfer (FRET) imaging methods provide unique insight into the
spatial distribution of energy transfer and (bio) molecular interaction events, though they …

We present a multimodal approach for measuring the three-dimensional (3D) refractive
index (RI) and fluorescence distributions of live cells by combining optical diffraction …
