An AIE-based bioprobe for differentiating the early and late stages of apoptosis mediated by H2O2†
Abstract
A bioprobe, TPE–Zn2BDPA, with aggregation-induced emission characteristics was designed and synthesized to differentiate the early and late stages of apoptosis mediated by H2O2. TPE–Zn2BDPA does not respond to healthy cells, but it selectively lights up the membrane of apopotic cells in both stages with brighter fluorescence in the late apoptotic stage.
