Although the concept of selective delivery has been postulated over 100 years ago, no
targeted nanomedicine has been clinically approved so far. Nanoparticles modified with …

The measurement of fluorescence spectra and the determination of fluorescence quantum
yields in transparent samples are conceptually simple tasks, but these procedures are …

Flexible metal‐organic materials are of growing interest owing to their ability to undergo
reversible structural transformations under external stimuli. Here, we report flexible metal …

Measurements of photon temporal correlations have been the mainstay of experiments in
quantum optics. Over the past several decades, advancements in detector technologies …

Optical super-resolution microscopy has revolutionized our understanding of cell biology.
Next to visualizing cellular structures with near-molecular spatial resolution, an additional …

Fundamental properties of light unavoidably impose features on images collected using
fluorescence microscopes. Accounting for these features is often critical in quantitatively …

The explosive growth of single-molecule techniques is transforming our understanding of
biology, helping to develop new physics inspired by emergent biological processes, and …

The counting of discrete photobleaching steps in fluorescence microscopy is ideally suited
to study protein complex stoichiometry in situ. The counting range of photobleaching step …

Metal–phenolic networks (MPNs) are amorphous materials that can be used to engineer
functional films and particles. A fundamental understanding of the heat-driven structural …

The particle-like nature of light becomes evident in the photon statistics of fluorescence from
single quantum systems as photon antibunching. In multichromophoric systems, exciton …
