The resulting antibiotic residue and organic chemicals from continuous climatic change, urbanization
and increasing food demand have a detrimental impact on environmental and human health
protection. So, we created a unique B, N-CQDs (Boron, Nitrogen doping carbon quantum dots) based
fluorescent nanosensor to investigate novel sensing methodologies for the precise and concentrated
identification of antibiotics and phenol derivatives substances to ensure that they are included in
the permitted percentages. The as-prepared highly fluorescent B, N-CQDs had a limited range of
sizes between 1 and 6 nm and average sizes of 2.5 nm in our study. The novel B, N-CQDs showed
high sensitivity and selectivity for phenolic derivatives such as hydroquinone, resorcinol, and para
aminophenol, as well as organic solvents such as hexane, with low detection limits of 0.05, 0.024,
0.032 and 0.013 µM respectively in an aqueous medium. The high fluorescence B, N-CQDs probes were
examined using transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier-transform
infrared spectroscopy (FTIR), and UV/VIS spectroscopy. The outcomes were compared to carbon
quantum dots (CQDs) previously generated from Urea |
