摘要

We show that bulk MoS2 can be efficiently exfoliated into ultrathin nanosheets in supercritical CO2 with ethanol as cosolvent. Moreover, such tailored MoS2 nanostructures, when they are directly used as labels for bioimaging, show excellent imaging effects with strong fluorescence and nontoxicity.
