Research Progress of Small Molecule Fluorescent Probes for Detecting Hypochlorite

Area of Science:

• Biochemistry
• Analytical Chemistry
• Medical Diagnostics

Background:

• Hypochlorous acid (HOCl), a reactive oxygen species (ROS), is produced by myeloperoxidase (MPO) from hydrogen peroxide and chloride ions.
• HOCl/OCl^- play significant roles in physiological and pathological conditions.
• Aberrant HOCl/OCl^- production can lead to tissue damage and various diseases, necessitating precise detection methods.

Purpose of the Study:

• To review recent advancements in fluorescent probes for hypochlorous acid detection.
• To provide insights for developing improved fluorescent probes for HOCl/OCl^-.
• To emphasize the importance of sensitive and selective detection of HOCl/OCl^-.

Main Methods:

• Literature review of recently developed fluorescent probes for HOCl detection.
• Analysis of probe characteristics including sensitivity, selectivity, and operational simplicity.
• Summarization of the progress in fluorescent probe methodologies for HOCl detection.

Main Results:

• Fluorescent probe methods offer simple operation, low toxicity, high sensitivity, and high selectivity for HOCl detection.
• Significant progress has been made in developing novel fluorescent probes for HOCl.
• These probes are crucial for monitoring HOCl in biological systems.

Conclusions:

• Fluorescent probes are effective tools for detecting hypochlorous acid.
• Continued development of these probes is essential for understanding HOCl's role in health and disease.
• This review offers valuable information for designing next-generation HOCl-sensing probes.
