  • Title: A highly specific red-emitting fluorescent probe for monitoring of Cu2+ in living cells and zebrafish.
    Author: Kong S, Zhang Y, Xie L, Qi G, Li Y, Dai H, Qi Q, Chen Y.
    Journal: Luminescence; 2024 Sep; 39(9):e4886. PubMed ID: 39285587.
    Abstract:
    A novel seminaphthorhodafluor-based fluorescent probe was designed and prepared. It exhibited an outstanding off-on fluorescence response (about 45-fold enhancement) to Cu2+ because the structure changed from a spirocyclic form to a ring-open state. It showed satisfactory detection performances for Cu2+ with fast response speed, high selectivity and anti-interference, and a low detection limit (22.9 nM) due to its long emission wavelength and off-on fluorescence response mode. This probe was also satisfactorily applied for the monitoring of Cu2+ in living cells and zebrafish.
