—Tracking Nanoparticle Growth “Synthesis: Labeling method sheds light on how nanoparticles take shape” A new technique enables scientists to follow nanoparticle growth with a “label”—a metallic seed that is distinguishable from the rest of the nanoparticle via electron microscopy. Using the method, Chad A. Mirkin of Northwestern University and coworkers have mapped how metallic nanoparticles change shape as they grow (Science, DOI: 10.1126/science.1225653). Knowing how nanoparticles evolve into certain shapes could help scientists better control the materials’ electronic and catalytic properties, the team says.
