Abstract
Fluorescent nitrogen-doped carbon dots (CDs) were prepared by a facile hydrothermal treatment from the waste biomass jackfruit peel. Structural, optical and morphological characterisation revealed that the functional groups on the surface of the CDs provided them with good aqueous solubility and excellent stability against different experimental conditions. From zeta potential analysis, the surface of the CDs was found to be negatively charged (-23.7 mV). The synthesized CDs could emit blue light under UV radiation and they act as efficient sensors for various analytes like metal ions, antibiotics, and dyes, etc. The CDs displayed outstanding sensing activity for the analytes with a low detection limit by a static quenching process. Fluorescence enhancement was obtained in the presence of levofloxacin also owing to the formation of hydrogen bonds between the surface functional groups on CDs and levofloxacin.
期刊介绍：
Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
