title: pH-driven conformational switch of "i-motif" DNA for the reversible assembly of gold nanoparticles.
abstract: Herein we demonstrate that gold nanoparticles conjugated to "i-motif" DNA behave like a pH dependent switch that undergoes reversible aggregations which can be easily visualized by the naked eye.
