A ratiometric fluorescent probe based on peanut-shell-derived CDs and CuNCs for smartphone-assisted detection of methyl orange.

Methyl orange (MO), a refractory azo dye, can persist in aqueous environments, creating a need for rapid and reliable monitoring methods. In this work, naturally O/N-containing peanut-shell biomass was utilized as an agricultural solid-waste precursor to synthesize oxygen-containing carbon dots (CDs) via a hydrothermal...
