Tryptophan functionalized framework of nanoporous material as fluorescent sensor for trace detection of Zn2+ ions

A novel fluorescent sensor of tryptophan functionalized mesoporous silica (Trp-Meso-Si) for detecting Zn2+ ion was designed by modifying the framework of nanoporous material with Tryptophan organic silicon source under the template via co-condensation method. Tryptophan organic silicon source was first synthesized by selecting natural amino acid as reagent via multi-steps reactions. The sensing material Trp-Meso-Si was well characterized by...
