Fertilization and early embryonic development as the beginning of a new life are key biological events. Hydrogen polysulfide (H S ) plays important roles during physiological regulation, such as antioxidation-protection. However, no report has studied in situ H S fluctuation during early embryonic development because of the low abundance of H S and inadequate sensitivity of probes.

However, the non-specific leak of the internal dyes in this approach is accompanied by false positive signals, resulting in inaccurate signal acquirement. To address this issue, in this work, we reported a novel signal amplification strategy with dye as a scaffold to construct a self-immolative dye-doped polymeric probe (SDPP).
