Fluorescence Detection of Hydrazine Hydrate Using Carbon Nanodots Synthesized from Mandarin Rind

Abstract

Hydrazine hydrate is a highly toxic chemical widely used in agricultural and pharmaceutical industries. Exposure to hydrazine can induce an irritation of respiratory tract, blindness, damage of the DNA and central nervous system. In this paper, we will show the hydrazine hydrate (N2H4) detection using fluorescence carbon nanodots synthesized from mandarin rind, the so-called R-CNDs. Highly sensitive detection can be seen by naked eyes in a fluorescence red-shifting and by analyzing absorption spectra in case of micromolar concentrations of hydrazine hydrate solution.

Fabrication, Characteristics, and Therapeutic Applications of Carbon‐Based Nanodots

“…Other key applications of carbon nanodots include the detection of luminescence or fluorescence of hydrazine hydrate and such compounds [100]. Furthermore, Sai et al [101] mention that carbon nanodots may effectively utilize UV light by acting as light conversion material.…”

“…These composite in Pickering emulsions exhibits the motions of coaxial electrosprayed NPs in response to changes in temperature [110]. Fluorescent carbon nanodots derived from mandarin peel can be used to detect micromolar amounts of hydrazine hydrate solution with exceptional sensitivity [100].…”
