摘要：

(Figure Presented) Functionalized mesoporous silica-based solids can be functionalized with e.g. guanidinium or polyol binding sites for detection of citrate and borate, respectively, in water. The solids are loaded with a dye (Fisheye; picture, left) that interacts with its binding sites. The dye is displaced by the target anions (○; right) and the corresponding anion is then detected by colorimetry. © 2005 Wilex-VCH Verlag GmbH & Co. KGaA.
