“…The fluorescence lifetimes of the carbon dots in absence and presence Fe 3+ ions were measured for the investigation of the mechanism of fluorescence quenching of Fe 3+ ions toward carbon dots. As shown in Figure S7B, the fluorescence lifetime of the carbon dots ions nearly did not change upon addition of Fe 3+ , suggesting that the mechanism of fluorescence quenching of Fe 3+ ions toward carbon dots can be attributed to static quenching (Jiang et al, 2019).…”

In this article, the Fe 3+-sensitive carbon dots were obtained by means of a microwave-assisted method using glutamic acid and ethylenediamine as reactants. The carbon dots exhibited selective response to Fe 3+ ions in aqueous solution with a turn-off mode, and a good linear relationship was found between (F 0-F)/F 0 and the concentration of Fe 3+ in the range of 8-80 µM. As a result, the as-synthesized carbon dots can be developed as a fluorescent chemosensor for Fe 3+ in aqueous solution. Moreover, the carbon dots can be applied as a fluorescent agent for fungal bioimaging since the fungal cells stained by the carbon dots were brightly illuminated on a confocal microscopy excited at 405 nm. Furthermore, an increase in the concentration of intracellular Fe 3+ could result in fluorescence quenching of the carbon dots in the fungal cells when incubated in the Tris-HCl buffer solution containing Fe 3+. However, due to EDTA might hinder Fe(III) to enter the fungal cells, incubation in Fe(III)-EDTA complex solution exerted negligible effect on the fluorescence of fungal cells labeled by the carbon dots. Therefore, the carbon dots can serve as a potential probe for intracellular imaging of Fe 3+ inside fungal cells.

“…CQDs were synthesized via a hydrothermal method [39] using all organs of Echinops persicus as the carbon source. Echinops persicus powder (6.0 g) was added to 75 mL distilled water, ultra-sonicated for 30 min at room temperature and then transferred to a 150 mL Teflon-lined autoclave.…”

Echinops persicus is a species of Echinops that can be found in Europe and western Asia especially in Iran. In this paper, the phytochemical properties of Echinops persicus were thoroughly investigated and studied. In this way, total amounts of flavonoid, tannins, phenols, carotenoids, saponins, alkaloids, and anthocyanin were measured by various analytical methods. The major phenolic and flavonoid content was found in the root acetone and flower ethanolic extract of the plant. Also, major saponins and carotenoid contents was found in root and leaf of the plant. These measurements were also performed for root, leaf, and flower of the plant in various solvent extracts. The results indicated that Echinops persicus is a rich source of secondary metabolites. Also, the plant extract demonstrated a considerable antiradical activity, which evaluated qualitatively as well as quantitatively. The largest capacity to neutralize DPPH radicals was found for root water extract of Echinops persicus plant. Finally, the possibility of the plant extract was evaluated for the green preparation of carbon quantum dots (CQDs). As-prepared CQDs were characterized by TEM, HRTEM, UV-Vis, XRD, and EDX analyses.

“…Dialysis is another purication method which is typically performed over a 24-72 h period to remove any remaining small soluble impurities. 6,16 These three methods are evenly implemented (Fig. 1b) (although in varying order) in green CD syntheses with the goal of minimizing the presence of any impurities.…”
