Rapid Detection of Bacteria by Carbon Quantum Dots
Journal of Biomedical Nanotechnology, 2011This work demonstrated a fluorescence measurement method for rapid detection of bacteria and their counting by using water-soluble carbon quantum dots (CQDs) as a fluorescence marker while sewage water bacteria were detection target bacteria. Highly luminescent water-soluble CQDs were prepared by carbonizing waste part of rice straw materials in a ...

Fluorescent carbon nanomaterials: “quantum dots” or nanoclusters?
Phys. Chem. Chem. Phys., 2014Despite many efforts, the mechanisms of light absorption and emission of small fluorescent carbon nanoparticles (C-dots) are still unresolved and are a subject of active discussion.

Carbon “Quantum” Dots for Fluorescence Labeling of Cells
ACS Applied Materials & Interfaces, 2015The specifically synthesized and selected carbon dots of relatively high fluorescence quantum yields were evaluated in their fluorescence labeling of cells. For the cancer cell lines, the cellular uptake of the carbon dots was generally efficient, resulting in the labeling of the cells with bright fluorescence emissions for both one- and two-photon ...

Observing Carbon Dots in Putative Boron Nitride Quantum Dots
Nano LettersBoron nitride quantum dots (BNQDs) have garnered a significant amount of attention in recent years due to their attractive optical properties, high stability, low toxicity, and good biocompatibility. However, our study reveals a critical mischaracterization in this field, demonstrating that some so-called BNQDs are, in fact, carbon dots (CDs) formed ...

Luminescence of carbon quantum dots in amorphous carbon
Journal of Optical TechnologySubject of study. The luminescence spectrum of amorphous protonated carbon (a-C:H) containing carbon quantum dots is studied. Aim of study. How the peak in the luminescence spectrum of a-C:H is affected by the presence of fragments with different configurations is determined. Method. The typical spectra are compared against those of the closest analogs:
