Highly sensitive fluorometric method based on nitrogen-doped carbon dot clusters for tartrazine determination in cookies samples

Gümrükçüoğlu, Abidin; Başoğlu, Aysel; Kolaylı, Sevgi; Dinç, Saliha; Kara, Meryem; Ocak, Miraç; Ocak, Ümmühan (2020)

Nitrogen-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 ...
A rapid and sensitive spectrofluorometric method for the determination of Au(III) based on fluorescence quenching of a 1,3,5-triphenyl-2-pyrazoline

Ocak, Ümmühan; Başoğlu, Aysel; Fandaklı, Seda; Yaylı, Nurettin (2018)

A simple, rapid, sensitive, and low-cost spectrofluorometric method was developed for the determination of Au(III) using 5-(2,3-dimethoxyphenyl)-3-(4-methoxyphenyl)-1-phenyl-4,5-dihydro-1H-pyrazole (L) in ethanol/water. ...
