On August 22, 1879, in a lecture to the British Association for the Advancement of Science, 1
Sir William Crookes announced that “radiant matter”(his term for the electrons emerging from …

Scanning transmission electron microscopy (STEM) of specimens in liquid, so-called Liquid
STEM, is capable of imaging the individual subunits of macromolecular complexes in whole …

Accurate determination of the size of nanoparticles has an important role in many different
scientific and industrial purposes, such as in material, medical and environment sciences …

We demonstrate that nanodiamonds fabricated to incorporate silicon-vacancy (Si-V) color
centers provide bright, spectrally narrow, and stable cathodoluminescence (CL) in the near …

The understanding of living systems and their building blocks relies heavily on the
assessment of structure–function relationships at the nanoscale. Ever since the …

Multi‐color, high spatial resolution imaging of fluorescent nanodiamonds (FNDs) in living
HeLa cells has been performed with a direct electron‐beam excitation‐assisted …

We present a phosphor nanoparticle that shows both upconversion luminescence (UCL)
and cathodoluminescence (CL). With this particle, low-autofluorescence, deep-tissue and …

Nanomaterials can be identified in high-resolution electron microscopy images using
spectrally-selective cathodoluminescence. Capabilities for multiplex detection can however …

The beam profile of an electron beam (EB) can be focused onto less than a nanometer spot
and scanned over a wide field with extremely high speed sweeping. Thus, EB is employed …

Cathodoluminescence (CL) microscopy is an emerging analysis technique in the fields of
biology and photonics, where it is used for the characterization of nanometer sized …
