Bright Future for Protein Nanoprobes: Berkeley Lab Researchers Discover New Rules for Single-Particle Imaging with Light-Emitting Nanocrystals
The term a "brighter future" might be a cliché, but in the case of ultra-small probes for lighting up individual proteins, it is now most appropriate. Researchers at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered surprising new rules for creating ultra-bright light-emitting crystals that are less than 10 nanometers in diameter. These ultra-tiny but ultra-bright nanoprobes should be a big asset for biological imaging, especially deep-tissue optical imaging of neurons in the brain.
Researchers at Berkeley Lab’s Molecular Foundry created upconverting nanoparticles (UCNPs) from nanocrystals of sodium yttrium fluoride (NaYF4) doped with ytterbium and erbium that can be safely used to image single proteins in a cell without disrupting the protein’s activity.

Antimony nanocrystals for batteries
Researchers from ETH Zurich and Empa have succeeded for the first time to produce uniform antimony nanocrystals. Tested as components of laboratory batteries, these are able to store a large number of both lithium and sodium ions. These nanomaterials operate with high rate and may eventually be used as alternative anode materials in future high-energy-density batteries.
