We present a facile, economical microwave pyrolysis approach to synthesize fluorescent carbon nanoparticles with electrochemiluminescence properties.
Carbon dots (or carbon quantum in some literature reports), generally small nanoparticles with various surface passivation effects, have attracted widespread attention recent years, a rapidly increasing number of research publications. The reported studies covered many aspects dots, from the development new synthetic methodologies to an improved mechanistic elucidation and exploration application opportunities, especially for those fluorescence imaging cells tissues. There also been...
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 dots, generally defined as small carbon nanoparticles with various surface passivation schemes, have emerged a new class of quantum-dot-like nanomaterials, their optical properties and photocatalytic functions resembling those typically found in conventional nanoscale semiconductors. In this work, dots were evaluated for photoinduced bactericidal functions, the results suggesting that highly effective bacteria-killing visible-light illumination. fact, inhibition effect could be...
This study reported the first assessment of carbon dots' (CDots) antiviral activity to human norovirus virus-like-particles (VLPs), GI.1 and GII.4 VLPs. CDots with different surface passivation molecules, 2,2'-(ethylenedioxy)bis(ethylamine) (EDA)-CDots 3-ethoxypropylamine (EPA)-CDots, were synthesized evaluated. The results indicated both EDA- EPA- highly effective inhibit strains VLPs' bindings histo-blood group antigens (HBGA) receptors on cells at concentration 5 µg/mL, EDA-CDots...
Enzyme-triggered in situ chromogenic and/or fluorogenic reactions under accessible conditions are significant for developing enzyme activity and related spectroscopic assays. Here, we describe a facile one-pot synthetic strategy to prepare silicon-containing nanoparticles with yellow-green fluorescence orange-red color by mixing N-[3-(trimethoxysilyl)propyl]ethylenediamine p-aminophenol (AP) aqueous solution at mild temperature. Encouraged the AP-regulated simple procedure generation of AP...
Background: Carbon dots (CDots) have recently been demonstrated their effective visible light-activated antimicrobial activities toward bacteria. This study was to evaluate and understand the roles of surface functionalities in governing activity CDots. Methods: Using laboratory model bacteria Bacillus subtilis, photo-activated three groups CDots with specifically selected different functionalization moieties were evaluated compared. The first group consisting by...
A novel, highly sensitive and selective dual-readout (colorimetric fluorometric) sensor based on fluorescent carbon dots (CDs) unmodified gold nanoparticles (AuNPs) for the detection of thiocyanate (SCN<sup>−</sup>) was proposed.
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...
Small carbon nanoparticles were functionalized by low-molecular weight amino compound 3-ethoxypropylamine (EPA) for ultracompact dots of bright fluorescence emissions. The results from solution-phase NMR characterization support the expected dot structure surface-attached with EPA species. optical properties EPA-carbon share many features those found in other surface functionalities, but there is an extra absorption shoulder blue spectral region, into which excitation much enhanced green...
Abstract Carbon dots, generally small carbon nanoparticles with various forms of surface passivation, have achieved the performance level semiconductor quantum dots in green spectral region, but their absorption and fluorescence red/near-IR are relatively weaker. Conceptually similar to endofullerenes, host-guest were designed prepared dyes encapsulated as guest nanoparticle core. Beyond desired enhancement optical properties, configuration may significantly broaden field dots.
Carbon dots prepared by using a hybrid approach are demonstrated for their photoexcited state properties and bactericidal activities.
The antiviral function of carbon dots (CDots) with visible light exposure was evaluated, for which the model bacteriophages MS2 as a surrogate small RNA viruses were used. results show clearly that light-activated CDots are highly effective in diminishing infectivity both low and high titer samples to host E. coli cells, effects dot concentration- treatment time-dependent. action apparently causes no significant damage structural integrity morphology phage or breakdown capsid proteins, but...
