摘要

Endogenous hydrogen peroxide is an important parameter associated with cellular signal transduction and homeostasis. However, abnormal H₂O₂ regulation in live systems has been implicated in many pathological conditions. Monitoring this signal in live systems is essential but challenging because current H₂O₂ probes are impractical for efficient bio-imaging due to UV/visible light as the excitation source. We herein present a novel design based on an organic fluorophore-attached lanthanide-doped upconversion nanoprobe (CYD1-UCNPs) for selective UCL detection of H₂O₂. This nanoprobe represents the next-generation imaging tool that features a robust UCL "turn-on" response to H₂O₂ with NIR-excited ratiometric signals and has potential applications in ratiometric UCL imaging of endogenous H₂O₂ generating in living cells and whole-body animals.
