Stepwise Thermal and Photothermal Dissociation of a Hierarchical Superaggregate of DNA-Functionalized Gold Nanoparticles

Hierarchical superaggregates consisting of DNA‐linked 14 nm AuNPs are synthesized and characterized by optical and scattering methods. Temperature changes, induced either thermally or photothermally, lead to a switching between specific sizes associated with superaggregates, primary networks, and in...
