Here, a novel and facile strategy for the fabrication of well-defined and uniform nanodimers as SERS substrates is presented. By the assistance of ultrasound, the violent polyol process for particle generation becomes controllable, enabling the self-assembly of nanostars to nanodimers. Moreover, the aggregation of nanodimers can be easily tuned by post-ultrasonic treatment, which gives a sensitive substrate for SERS.en1521-37652020612431248aggregationnanodimersself-assemblysurface-enhanced Raman spectroscopyultrasonic-assisted synthesisTechnology::600: TechnologyJournal Article10.1002/chem.201904518Journal Article
