“…[17][18][19]22 The medical research conrmed that acetone is a biomarker for type-1 diabetes in which the deciency of insulin in the pancreas induces the body cells to fatty acids breakdown and produce acetone rather than react with glucose. 18,23 Various techniques have been used for the detection of acetone as acetone vapor detectors such as screen-printed TiO 2 nanoparticles, silicon doped WO 3 NPs, MoO-CdO NPs, and ZnO nanoowers. 18,20,24 The uorescence technique to target acrylamide and acetone offers fast response, high sensitivity, excellent selectivity, and good precision with avoiding the disadvantages of the conventional detection methods.…”

“…Acetone nowadays has wide applications as a cosmetic solvent or denaturant, therefore it is present at trace levels or even elevated concentrations in the environment, resulting from leakage of industries or sewerage ejection. Since acetone is highly volatile and potentially possesses toxicity on humans, detection of acetone in water has been of increasing attention [1,2]. Furthermore, urinary acetone or that in the circulation can be detected as a promising biomarker for diagnosing diseases, including diabetes mellitus or starvation [3,4].…”

Carbon dots (CDs) are an emerging family of nanostructures due to their unique optical properties, high chemical stability, biocompatibility, and low toxicity, they have been able to attract a lot of attention and cause significant changes in various scientific fields. In this study, the green synthesis of stable CDs by hydrothermal and pyrolysis methods (H-CDs and P-CDs) is performed from Nigella sativa seeds as a natural precursor. Using these methods, the formation and the surface passivation of the CDs are done simultaneously, resulting in the intrinsic fluorescence emission. The as-prepared CDs are characterised by UV-vis spectroscopy, fluorescence spectroscopy, elemental analysis, dynamic light scattering, Fourier transform infrared spectroscopy, and transmission electron microscopy, from which their structural information and property are interpreted. The fluorescence intensity graph of H-CDs and P-CDs, with excitation wavelengths in 360 nm, shows the highest emissions at 430 and 410 nm, respectively. Particle size distribution was obtained at about 4 nm. The fluorescent quantum yield (QY) of H-CDs and P-CDs was measured to be 7% and 2%, respectively. The synthesised CDs showed good photoluminescence (PL) responses to acetone solution. Acetone had a different effect on the PL properties of CDs obtained from pyrolysis and hydrothermal methods so that in P-CDs, it increased the intensity of PL, and in H-CDs; it decreased the intensity of PL.
