Abstract

Seeing red: Highly sensitive and selective chemical sensing systems were developed for the naked-eye detection of toxic ions by the direct and indirect postgrafting of hydrophilic and hydrophobic chromophores into spherically nanosized cavities of cubic Fm3m monoliths (HOM-C10). This leads to reliable control over the visual detection of toxic metals such as Pb^II, Cd^II, Sb^III, and Hg^II ions at a low concentrations (≈10^-9 M). DZ = diphenylthiocarbazone. (Figure Presented).
