Background:

• Azide groups are important functional groups in chemical biology and materials science.
• Accurate quantification of azide groups is crucial for various applications, including drug delivery and diagnostics.
• Existing methods for azide quantification can be complex or lack sensitivity.

Purpose of the Study:

• To develop a novel, sensitive, and straightforward method for quantifying azide groups.
• To enable the measurement of azide groups on both solid surfaces and proteins.
• To utilize a clickable and cleavable fluorescent probe for azide detection.

Main Methods:

• A novel clickable and cleavable fluorescent compound was synthesized.
• The compound was used to conjugate with azide groups on a solid surface and a protein.
• A subsequent cleavage reaction liberated the fluorophore into the solvent.
• The liberated fluorophore was quantified using a conventional fluorometer.

Main Results:

• The method successfully quantified azide groups on solid surfaces.
• The method also accurately quantified azide groups on proteins.
• The fluorescent signal correlated with the number of azide groups present.
• The assay is simple and can be performed with standard laboratory equipment.

Conclusions:

• This novel method provides a simple and effective way to quantify azide groups.
• The technique is versatile and applicable to both material surfaces and biomolecules.
• This approach has potential applications in various fields requiring azide group detection.
