Fluorimetric vitamin B2 sensor study using CQDs synthesized by thermal method

Abstract

In this study, carbon quantum dots (CQDs) were synthesized through the thermal method and it is aimed to test the sensor sensitivity to vitamin B2 in fluorimetric measurements with CQDs. Therefore, for this study, CQDs were synthesized from glutathione by the thermal method, and to observe the distribution of CQDs among B2 vitamins in AFM, their nano size was measured by atomic absorption microscopy (AFM) and their morphological structure among B12 vitamins was examined by scanning electron microscopy (SEM). After these characterizations, the fluorimetric study will be carried out and the limit of detection (LOD) and limit of quantification (LOQ) will be calculated by taking fluorescence peaks against vitamin B2 at different concentrations. LOD and LOQ values are expected to be around 12- 20 and 36-40 µM, respectively. This study is a study that will shed light on sensor studies for vitamin B2, its derivatives and other vitamins.
