Fluorescent Probes for Aldehyde Detection in Biological Systems: Design Principles, Spectroscopy, and Emerging Applications
This review compares the six main conjugation chemistries that underlie current probe design—2-aza-Cope/Mannich cascade, hydrazone/oxime formation, Michael addition, Schiff base condensation, and 2-aminothiophenol cyclization—alongside the three photophysical strategies used to convert these reactions into quantitative...
