Single-particle tracking (SPT) is a powerful technique to elucidate the behavior of biomolecules inside or on the surface of living cells in real time. SPT is based on labeling the component of interest with a phosphor or a light-scattering gold nano

The authors describe the preparation of Eu3+-doped GdVO4 nanocrystals (NCs) by precipitation of the Cd3+(Eu3+)-citrate complex which was then converted to the respective vanadate by dialysis. The fractions of Eu3+ ranged from 5 to 100 mol%. The NCs w

Upconverting luminescent nanoparticles (UCNPs) represent an interesting class of nanomaterials for bioanalytical applications. Due to their excitation in the near infrared region of the spectra, no fluorescence of biological compounds is trigged. Com
