A highly sensitive and water-soluble âswitch-onâ fluorescent probe with aggregation-induced emission characteristics was developed for protein quantification and visualization. It offers a rapid, economic and effective way for the assay of complete serum proteins and disease-marker proteins.
The self-assembly of diphenylalanine peptides (L-PheâL-Phe) into microtubes with âturn onâ bright yellow green fluorescence was described, which was achieved using an aggregation-induced emission (AIE) molecule of 9,10-bis[4-(3-sulfonatopropoxyl)-styryl] anthracene (BSPSA) sodium.
