Highly Sensitive Detection

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.

Abstract An ionic liquid-based thin (~ 1 µm) colorimetric membrane (CM) is a key nano-tool for optical ion sensing, and a two-dimensional photonic crystal slab (PCS) is an important nano-platform for ultimate light control. For highly sensitive optical ion sensing, this report proposes a hybrid of these two optical nano-elements, namely, a CM/PCS hybrid. This structure was successfully fabricated by a simple and rapid process using nanoimprinting and spin-coating, which enabled control of the CM thickness. Optical characterization of the hybrid structure was conducted by optical measurement and simulation of the reflection spectrum, indicating that the light confined in the holes of the PCS was drastically absorbed by the CM when the spectrum overlapped with the absorption spectrum of the CM. This optical property obtained by the hybridization of CM and PCS enabled drastic improvement in the absorption sensitivity in Ca ion sensing, by ca. 78 times compared to that without PCS. Experimental and simulated investigation of the relation between the CM thickness and absorption sensitivity enhancement suggested that the controlled light in the PCS enhanced the absorption cross-section of the dye molecules within the CM based on the enhanced local density of states. This highly sensitive optical ion sensor is expected to be applied for micro-scale bio-analysis like cell-dynamics based on reflectometric Ca ion detection.
