Highly sensitive fluorometric method based on nitrogen-doped carbon dot clusters for tartrazine determination in cookies samplesGümrükçüoğlu, AbidinBaşoğlu, AyselKolayli, SevgiDi̇Nç, SalihaKara, MeryemOcak, MiraçOcak, ÜmmühanAmorphousCarbon dotCookieDetermination methodFluorescenceTartrazineNitrogen-doped carbon nanodots (CDs) were prepared via the solvothermal method, using urea and triethylene glycol as the starting materials. The as-prepared CDs had individual diameters of approximately 100 nm and were in clusters of different sizes. The surface composition and optical properties of the as-prepared CDs were characterized. They exhibited multicolor emission properties in the visible range when excited with a wide wavelength range. The aqueous solution of the CDs was used in highly sensitive tartrazine determination. The fluorescence quenching of the CDs was in a linear relationship with the concentrations of tartrazine in the range of 0.5–30.0 µM. The detection limit of the assay was 0.18 µM. Acceptable recovery results were obtained via spike-recovery experiments on cookie samples.TUBITAK2020Articlehttps://rdlopen.rawdatalibrary.net/r/gumushane/14659https://doi.org/10.3906/kim-1903-281300-0527enTurkish Journal of Chemistryinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/14659
