The synthesis of fluorescent carbon quantum dots for tartrazine detection in meals: a novel one-step microwave heating method: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0

Summary

These days, carbon quantum dots (CDs) as semiconductor synthesized nanoparticles have develop into a sexy topic for plenty of purposes resulting from their outstanding options. Within the present research, the extremely fluorescent (FL) CDs with nice traits have been synthesized via a novel one-step microwave irradiation by citric acid monohydrate and urea as carbon precursors. The as-prepared CDs have been quasi-spherical form with a mean diameter of 4.5 nm and emitted vibrant blue FL beneath ultraviolet gentle irradiation (UV). Moreover, the synthesized CDs possessed totally different properties similar to various purposeful teams, good sensitivity and selectivity, excessive water-solubility, low toxicity, and vital stability in varied environmental circumstances. The outcomes indicated that the as-prepared CDs could be utilized as a fluorescent probe for detection of various concentrations of tartrazine from 5 to 100 µM in meals samples. As well as, the findings revealed that the nice linear relationship was obtained between the FL depth of CDs and totally different concentrations of tartrazine over the vary of 5 to 100 µM with the detection restrict of two.58 µM.
