Multi-scene visual hydrazine hydrate detection based on a dibenzothiazole derivative

Area of Science:

• Analytical Chemistry
• Environmental Science
• Biomedical Imaging

Background:

• Industrial hydrazine (N2H4) poses significant ecological and human health risks.
• Developing sensitive and selective detection methods for hydrazine is crucial for environmental and biological monitoring.

Purpose of the Study:

• To develop a novel fluorescent probe for detecting hydrazine.
• To evaluate the probe's performance and applicability in real-world samples.

Main Methods:

• Synthesis of a novel dibenzothiazole derivative (DBTD) as a fluorescent probe.
• Spectroscopic analysis (colorimetric and fluorescent) for hydrazine detection.
• Application of the probe in water, cell, and zebrafish samples.
• Fluorescence colocalization studies to assess cellular targeting.

Main Results:

• The DBTD probe exhibited strong colorimetric detection and rapid response to hydrazine.
• High selectivity and sensitivity were achieved, with a detection limit of 0.438 μM.
• Successful determination of trace hydrazine in environmental and biological samples (water, cells, zebrafish).
• Fluorescence colocalization confirmed the lysosomal-targeting capability of the DBTD probe.

Conclusions:

• The novel DBTD probe is a highly effective tool for sensitive and selective hydrazine detection.
• The probe's applicability in diverse matrices highlights its potential for environmental and biological monitoring.
• The lysosomal-targeting ability of DBTD opens avenues for intracellular hydrazine imaging.
