Key Points

To develop a ratiometric fluorescent platform for the detection of ethephon (ETH).
Developed a hybrid probe using UiO-66-NH₂ and red carbon dots.
Integrated the probe with smartphone technology for quantitative analysis.
Synthesized red carbon dots from green waste materials.
Successfully detected ethephon levels visually and quantitatively.
Demonstrated real-time detection capabilities.
Achieved significant fluorescence intensity changes with varying ethephon concentrations.

Implication

Ratiometric platform enables on-site detection of ethephon using smartphone technology, suggesting practical applications.

Abstract

A smartphone-integrated ratiometric fluorescent platform was developed for on-site quantitative and visual detection of ethephon (ETH) using a UiO-66-NH₂/red carbon dots (R-CD) hybrid probe. The R-CDs were synthesized from green...
