Protein misfolding and metal dishomeostasis are two key
pathological factors of Alzheimer’s disease. Previous studies have showed that Cu‐mediated Aβ aggregation pathways lead to formation of neurotoxic Aβ oligomers. Herein, we reported a series of picolinic acid‐based Cu‐activatable sensors, which can be used for the fluorescence imaging of Cu‐rich Aβ aggregates.
