摘要：
Fluorescence Lifetime Imaging Microscopy (FLIM) has been employed for the detection of intracellular Zn2+ levels, implicated in various signalling pathways, using a family of quantum dot (QD) nanosensors. The sensing mechanism was based on photoinduced electron transfer (PET) between an azacycle receptor group and the QD nanoparticles.
