Simple synthesis of water-soluble ruthenium carry CDs as admirable probe for improved environment and biological applications

Simple devising of N-doped carbon dots (N-CDs) as a low-cost probe for selective environmental toxin detection and security applications

“…The (002) plane was consistent with an amorphous region described in earlier reports. 46 Along with the HR-TEM data, the XRD reports prove that N-CDs are amorphous in nature.…”

Carbon Dots: A Multifunctional Nano‐Sized Giant Tool for the Detection Probe and Physical Reformation of NiMoO4 in Solid‐State for Enriched Energy Storage Application

“…[11] Next, the Gaussian-fitted Mo 3d spectrum (Figure 3e, top) shows two peaks at 231.7 and 234.9 eV, which parallels Mo 3d5/2 and Mo 3d3/2, confirming the Mo 6+ oxidation state. [22] There was a significant difference in Ni 2p 3/2 (Figure 3d, bottom), Mo 3d 5/2 and Mo 3d 3/2 (Figure 3e, bottom), binding energy peak position in NM-CDs (15), followed by C1s spectra (Figure S1f, Supporting Information) of deconvoluted into 284.5, 285.9, and 287.8 eV refers to C═C, C─N, and C─O species of CDs, [1] which confirms the existence of CDs along with NM. At last, the N1s spectra show (Figure 3g) a peak positioned at 398.9 eV, establishing the presence of C═N moieties.…”

“…Followed by the Stern-Volmer quenching constant observed as 1 × 10 4 , 1.8 × 10 4 , and 3.3 × 10 4 m −1 , respectively, was calculated from the graph of linear range plots, and the variation in the PL intensity with increasing concentration of the pollutants (analytes) well fitted with Stern-Volmer equation.

“…CDs are a unique DOI: 10.1002/adsu.202300419 material because of their excellent traits: high water solubility, electron-rich functional groups, less toxicity, easy tailoring optical properties, and good electrical conductivity. [1] The properties mentioned above are the primary reason for employing CDs in entire scientific research areas such as biomedical, drug delivery, bio-imaging, antibacterial, anticancer bio-sensors, metal ions sensors, supercapacitors, battery, electrocatalysis, photocatalysis, catalysis, solar cells, and LED. [2,3] In the past few decades, uncountable methods have been grown for CDs preparation: hydrothermal/solvothermal, ultrasonication, thermal-pyrolysis, electrochemical, and microwave-assisted methods.…”
