Fluorescent Carbon Dots for Sensitive Detection and Bioimaging
This community develops carbon-based nanomaterials, primarily carbon dots and quantum dots, to create highly sensitive and selective fluorescent probes for detecting chemical species and imaging biological cells.
The research focuses on the synthesis of carbon dots, often using green methods or nitrogen-doping to enhance optical properties. These materials are engineered for ratiometric fluorescence, allowing for precise, selective detection of ions, pharmaceuticals, and other analytes. Key applications include cell imaging and the development of fluorescent sensors for food safety and environmental monitoring. The work emphasizes high sensitivity and selectivity, frequently employing molecularly imprinted techniques to target specific molecules. While some studies explore energy storage and catalytic mechanisms, the dominant thread is the use of these nanomaterials as optical tools for chemical analysis and biomedical visualization.
The community is most prominent in research tracked for Terbium, where it accounts for 2.9% of all Terbium research, and Europium, where it represents 1.5% of that element’s output. It also contributes 0.9% of Nitrogen research and 0.7% of Carbon research, with Nitrogen and Carbon together accounting for over 2,400 papers in this group.
The community comprises 16,451 papers, with the highest publication volume in Microchemical Journal, Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, and Food Chemistry.
Recent work continues to focus on dual-mode sensing platforms for food safety, such as detecting antibiotics in food samples, and explores the use of carbon dots in sustainable food packaging and optoelectronic devices.
