Abstract

Carbon dots produced hydrothermally from algae were used directly for H₂O₂ sensing. The mineral nutrients in biomass were found be important for the composition, crystallinity, dispersion and photoluminescence (PL) quenching of the carbon dots under reactive oxygen species, which catalysed the oxidation of passivating ligands.
