Abstract
We have synthesized Murraya Koenigii leaves powder-derived carbon nanodots (CNDs) by hydrothermal method. A tribute to our commitment to environmental sustainability is the unique composition of our CNDs, which are made entirely of natural carbon sources and a green solvent, water. Our further efforts to improve performance led us to start making nitrogen-doped CNDs. By using urea as a non-toxic source of nitrogen, we observed a substantial increase in fluorescence intensity, extending the usefulness and potential of these nanomaterials. We investigated the optical properties using UV-Vis and fluorescence spectroscopy. The other parameters, like structural and size-shape morphology, were analyzed using FTIR, XRD, and HR-TEM, respectively. The fluorescence spectroscopy demonstrated their capability to exhibit wavelength-dependent photoluminescence (PL), highlighting the potential of these CNDs for cell bioimaging applications. The fluorescence properties affirm their suitability for biomedical applications, as they do not involve any inherent risk to cells.
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.
