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

Approaching Tryptophan-Derived Polynorbornene Fluorescent Chemosensors: Synthesis, Characterization, and Sensing Ability for Biomedical Applications as Biomarkers for Detecting Fe2+ Ions

“…Tryptophan (Trp), an amino acid, is known for its intrinsic fluorescence, which is quenched through resonance energy transfer or electron mechanisms upon interaction with ligands, such as metal ions. , This characteristic has driven extensive exploration of Trp in the research field for the design of fluorescent-based chemosensors. − Significant progress has been achieved in synthesizing fluorescent molecular probes and polymer-based fluorescent probes incorporating Trp. For instance, a Trp-based turn-off molecular chemosensor demonstrated selective detection of Fe 2+ , effectively discriminating the ion from tap and drinking water .…”
