Nanoparticle dyes boost storage

Shrinking the size of fluorescent dye particles is one way to cram more information into optical data storage devices, but dye particles can be made only so small. Researchers from the University of Toronto have found a way to put layers of different dyes into a single particle, making it possible to record several bits of data on the same spot. The technique could increase data storage capacities several-fold, and improve anticounterfeiting measures.
