Stimuli-responsive plasmonic core-satellite assemblies: i-motif DNA linker enabled intracellular pH sensing

Chem Commun (Camb). 2013 Jun 28;49(51):5739-41. doi: 10.1039/c3cc80005a.

Abstract

We report stimuli-responsive core-satellite assemblies of binary gold nanoparticles, linked by i-motif DNA, for live cell plasmonic imaging of pH changes in the endocytic pathway.
