Robust transparent mesoporous silica membranes as matrices for colorimetric sensors

Transparent functionalized mesoporous silica membranes have been prepared with high surface areas ([similar]500 m2 g−1) that exhibit high sensitivities for colorimetric detection and sensing of dilute heavy-metal ions (e.g., Pb2+).
