The basic theory and principles of the multiple-wavelength anomalous solvent-contrast (MASC) method are introduced as a contrast-variation technique for generating low-resolution crystallographic phase information on the envelope of a macromolecule. Experimental techniques and practical considerations concerning the choice of anomalous
We introduce a compact array fluorescence sensor principle that takes advantage of the long luminescence lifetimes of upconversion nanoparticles (UCNPs) to deploy a filter-free, optics-less contact geometry, advantageous for modern biochemical assays of biomolecules, pollutants or cells. Based on technologically

The incorporation of Se and Yb into the eyes of mice has been studied. Selenodiglutathione, (GS)2Se, or ytterbium chloride, YbCl3, were injected intraperitoneally into mice: either alone, combined, or after various time intervals. Instrumental neutron activation analysis was applied as

We report a new sensor for the specific detection of lead ions (Pb2+) in contaminated water based on fluorescence resonance energy transfer (FRET) between upconversion nanoparticles (UCNPs) as donors and gold nanoparticles (Au NPs) as receptors. The UCNPs modified with
Rare earth elements are vital in everyday life worldwide: catalysts in cars, colors in screens, magnets in electronics. Essential for modern living.
