| Outline of Final Research Achievements |
Fluorescence detection of glycosidase was investigated on the basis of aggregate emission of benzothiadiazole-triphenylamine donor-acceptor dyes. The parent donor-acceptor dye, which is fluorescent only in the aggregate state, indicated a decrease of emission intensity by introducing galactopyranoside moiety. In contrast, the emission intensity was recovered and enhanced upon addition of galactosidase, which reacted with the galactopyranoside moiety to release the fluorescent parent donor-acceptor dye, leading to the emission enhancement in the aggregate state. As a result of the emission enhancement, the galactosidase detection can be achieved.
