Abstract
Peroxynitrite (ONOO−) plays a pivotal role in various physiological and pathological processes. The sensitive and specific detection of ONOO− is of paramount significance for early diagnosis, treatment, and prognosis of diseases. In this study, a near-infrared (NIR) fluorescent probe was developed for the detection of ONOO− with rapid responsiveness (less than 100 s). As the concentration of ONOO− increases, the ratio of fluorescence intensities exhibited a robust linear relationship with ONOO− concentration. Additionally, the probe demonstrated the ability to selectively detect changes in ONOO− levels, with a limit of detection (LOD) value of 13 nM. Importantly, the probe was successfully employed to detect endogenous ONOO− in living cells and mouse models. In conclusion, the fluorescent probe exhibits significant potential for elucidating disease processes induced by ONOO−.
期刊介绍:
Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied.
Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media.
The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
