Ratiometric SERS Sensor with Schiff-Base Reaction and Solvent Internal Standard for High-Precision Detection of Hydrazine
Hydrazine (N2H4) is a widely used industrial chemical yet poses severe toxicity risks to human health and ecological systems. It is highly urgent to develop rapid, reliable, and accurate analytical methods for trace N2H4 monitoring. Surface-enhanced Raman spectroscopy (SERS) offers distinct advantages for trace analy...
