A Photostable AIE Luminogen for Multifunctional Three-photon Bioimaging
In this study we realized multiphoton bioimaging,by utilizing a kind of fluorescent agent with aggregation induced emission(AIE)feature.The luminogen is called tetraphenylethene-triphenylphosphonium(TPETPP),and it is a highly specific mitochondria tracker.We studied its photostability under three-photon excitation,and found that even under long-term excitation,the three-photon fluorescence signals of TPETPP in the cells still kept very bright.Furthermore,under the same 1020 nm femtosecond excitation,TPETPP assisted three-photon imaging has higher spatial resolution than two-photon imaging of MitoTracker red FM(MT),which is a commercially available mitochondria imaging agent.
