Quantum dots (QDs) generally refer to nanoscale particles of conventional semiconductors that are subject the quantum-confinement effect, though other nanomaterials similar optical and redox properties also named as QDs even in absence strictly defined quantum confinement. Among such have attracted tremendous recent interest carbon dots, which small nanoparticles with some form surface passivation, graphene various configurations. In this article, we highlight these carbon-based by focusing...
There has been much discussion on the need to develop fluorescent quantum dots (QDs) as ultracompact probes, with overall size profiles comparable those of genetically encoded tags. In use conventional semiconductor QDs for such a purpose, beautifully displayed dependence fluorescence color particle diameter becomes limitation. More recently, carbon have emerged new platform QD-like nanomaterials. The optical absorption and emissions in are not bandgap origin, different from QDs. absence any...
Carbon-based "quantum" dots or carbon are surface-functionalized small nanoparticles. For bright fluorescence emissions, the nanoparticles may be surface-doped with an inorganic salt and then same organic functionalization. In this study, without ZnS doping were prepared, followed by gel-column fractionation to harvest of 40% 60% in quantum yields, respectively. These highly fluorescent evaluated for optical imaging mice, from which images obtained. Of particular interest was observed...
Carbon soot from overcooked barbecue meat was used as a precursor for brightly fluorescent carbon dots and their serving potent visible-light photocatalysts, similar to those other nanoscale sources, thus demonstrating the versatility of in terms structure, composition, properties.
Fluorescence intensities of carbon dots are substantially enhanced in the confined environment polymeric films.
The carbon dots in this study were small nanoparticles with the particle surface functionalized by oligomeric poly(ethylene glycol) diamine molecules. Upon photoexcitation, brightly fluorescent aqueous solution served function of excellent electron donors to reduce platinum(IV) and gold(III) compounds into their corresponding metals be deposited on dot surface. even very amounts found have dramatic quenching effects fluorescence emission intensities, but essentially no observed decays....
Carbon "quantum" dots (or carbon dots) have emerged as a new class of optical nanomaterials. Beyond the widely reported bright fluorescence emissions in dots, their excellent photoinduced redox properties that resemble those found conventional semiconductor nanostructures are equally valuable, with photon-electron conversion applications from photovoltaics to CO2 photocatalytic reduction. In this work we used gold-doped controlled synthesis water-soluble catalysts for closer examination...
A precise probe that can be applied in a variety of situations, such as both environmental sensor and vitro imaging, is very attractive promising. Here, we firstly reported kind nitrogen-rich carbon dots (N-CDots) growing during hydrothermal treatment, which emit bright colorful fluorescence utilized reliable for Ferric ions (Fe3+) detection bio-imaging. The nitrogen/carbon molar ratio (N/C) N-CDots high 39.9%. It the nitrogen content provides quantum yield (at excitation wavelength 365 nm,...
Carbon nanoparticles are in all of the carbon nanomaterials that presently widely pursued for potential bioapplications, but their vivo biodistribution-related properties largely unknown. In this work, highly 13C-enriched were prepared to allow quantification biological samples by using isotope-ratio mass spectroscopy. The biodistribution results presented and discussed, also compared with those aqueous suspended nanotubes reported previously. distribution profile time dependencies similar...
Carbon–semiconductor hybrid quantum dots are classical carbon with core nanoparticles doped a selected nanoscale semiconductor. Specifically, on those the TiO2 doping, denoted as CTiO2-Dots, their synthesis and thorough characterization were reported previously. In this work, CTiO2-Dots evaluated for visible light-activated antibacterial function, results showing effective killing of not only Gram-positive but also generally more resistant Gram-negative bacteria. The clearly potent agents...
