过氧亚硝酸盐(ONOO−)是一种在体内形成的强大而短暂的氧化剂,可以直接与大多数生物分子反应。为了充分了解ONOO−在细胞生物学中的作用,需要改进ONOO−的选择性检测和实时分析方法。我们提出了一种水溶性,发光铕(iii)探针的快速和灵敏的检测过亚硝酸盐在人血清,活细胞和生物基质。我们利用探针的长发光寿命以时间分辨的方式测量ONOO−,有效地避免了生物样品中自发荧光的影响。为了证明Eu(iii)探针的实用性,我们监测了不同细胞系中ONOO−的产生,随后用临床上常用的冷大气等离子体装置进行皮肤伤口治疗。基于反应性的铕(iii)探针对过氧亚硝酸根(ONOO−)具有出色的选择性,使其能够在活细胞中进行时间分辨发光检测。
Peroxynitrite (ONOO−) is a powerful and short-lived oxidant formed in vivo, which can react with most biomolecules directly. To fully understand the roles of ONOO− in cell biology, improved methods for the selective detection and real-time analysis of ONOO− are needed. We present a water-soluble, luminescent europium(iii) probe for the rapid and sensitive detection of peroxynitrite in human serum, living cells and biological matrices. We have utilised the long luminescence lifetime of the probe to measure ONOO− in a time-resolved manner, effectively avoiding the influence of autofluorescence in biological samples. To demonstrate the utility of the Eu(iii) probe, we monitored the production of ONOO− in different cell lines, following treatment with a cold atmospheric plasma device commonly used in the clinic for skin wound treatment. Reactivity-based europium(iii) probe displays excellent selectivity for peroxynitrite (ONOO−), enabling its time-resolved luminescence detection in living cells.
