The suspense of dispersion! Nanoparticle clusters with a hydrolyzable interparticle barrier have been synthesized. These clusters are able to disperse into a stable colloid at a rate dependent upon the pH of the surrounding solution (see figure). This method could enable novel applications for colloidal clusters paired with environmentally responsive materials.
