A renewable test strip combined with solid-state ratiometric fluorescence emission spectra for highly selective and fast determination of hydrazine gas

Abstract

N2H4 is one of the most toxic and explosive chemicals. Especially, N2H4 vapor will become dangerously unstable. However, the determination of N2H4 gas has lagged behind the detection of N2H4 in aqueous solution or biological fluid in the crucial ability to discriminate and quantify N2H4. Despite a multitude of fluorescent probe-coated test strips were used for N2H4 gas, these techniques are mainly through the eye observation of fluorescence color changes, which will hamper the discrimination of a subtle color changes on test strips due to the limited capacity of eyes in perceiving and differentiating colors. Herein, we developed a new technique combining a renewable test strip and solid-state ratiometric fluorescence readout. The results confirmed that the prepared test strips could be used as the solid-state fluorescence sensor for fast capture (within 5 min) and quantification of N2H4 gas. Additionally, the test strips could be easily renewable. Thus, this test strip-based approach provides an efficient tool for N2H4 gas detection, which is particularly significant for the real-time monitoring of N2H4 gas in airport and environmental atmosphere at a chemical plants region. This design concept presents a new avenue for developing solid-state fluorescence sensors for gas detection.
