Conspectus Lanthanide-doped upconversion nanoparticles (UCNPs) are a special class of
luminescent nanomaterials that convert multiwavelength near-infrared (NIR) excitation into …

Electrogenerated chemiluminescence microscopy (ECLM) provides a real-time imaging
approach to visualize the surface-dependent catalytic activity of nanocatalysts, which helps …

Super-resolution microscopy (SRM) is a fast-developing field that encompasses
fluorescence imaging techniques with the capability to resolve objects below the classical …

Super-resolution microscopy has become an increasingly popular and robust tool across the
life sciences to study minute cellular structures and processes. However, with the increasing …

Stimulated emission depletion microscopy provides a powerful sub-diffraction imaging
modality for life science studies. Conventionally, stimulated emission depletion requires a …

Despite its short history, diffraction-unlimited fluorescence microscopy techniques have
already made a substantial imprint in the biological sciences. In this review, we describe …

Since its initial demonstration in 2000, far-field super-resolution light microscopy has
undergone tremendous technological developments. In parallel, these developments have …
