A turn-on fluorescent probe for cysteine with high selectivity was designed and synthetized. The probe can be used for “naked-eye” detection of Cys with an obvious color change from yellow to colorless. The probe could be applied for Cys detection in real human serum.
In this work, a novel purine based probe PTAHN was successfully designed and synthesized. PTAHN displayed high selectivity towards Zn2+via turn-on fluorescence. What's more, PTAHN can be proficiently employed for imaging Zn2+ in living cells.
A Cd(ii) metal–organic framework, {NH2(CH3)2·Cd2.5(L)2(H2O)·(H2O)}n (H3L = tricarboxytriphenylamine), featuring a 3D microporous framework with two different types of 1D channel has been synthesized and used for the naked-eye detection of Cu2+ ions.
A new type of hydrogel-coated paper sensor was developed for the semiquantitative and naked-eye detection of Cu2+ ions with high selectivity and good regenerability.
We developed a novel strategy for signal amplification strategy using a visible light-induced photopolymerization, initiated by a selective turn-on photoredox catalyst. As photoredox catalysts, fluorescein derivatives are able to initiate...
