A colorimetric and ratiometric fluorescent probe (Cou-BPO) was prepared for food analysis and cell imaging; it showed high selectivity, sensitivity, visible and fast response towards BPO via a selective oxidation cleavage-induced cascade reaction.
A new CdTe@SiO2@CdSe nanohybrid was demonstrated for the ratiometric fluorescence detection of Cd2+via the turn-on model and “ion-imprinting” technique.
A dual-recognition carbon dots-based nanoprobe with controllable G-quadruplex release is developed for ratiometric fluorescence detection of pathogenic bacteria in a fast and precise way, which opens a promising avenue for...
