Abstract:
A new two-photon fluorescence probe for endogenous peroxynitrite (ONOO-) detection was designed and synthesized. The probe exhibits good selectivity and sensitivity for ONOO- in phosphate-buffered saline solution with a low detection limit (3.5 × 10-8 M). Furthermore, the probe displays good performance in detecting endogenous ONOO-, not only in RAW 264.7 cells but also in rat hippocampal tissue, with a high two-photon cross-section value (δ ≈ 100 GM) at a deep depth of 120 μm.
