Synthesis of N,Si co-doped carbon dots to establish a fluorescent sensor for Hg(ii) detection with triple signal output

Abstract

Mercury is deemed as the heavy metal with extreme toxicity. Thus it is of significance to develop effective method for mercury ions detection with high performances. In the work, carbon...

Carbon Dots: Synthesis, Characterizations, and Recent Advancements in Biomedical, Optoelectronics, Sensing, and Catalysis Applications

“…The exceptional linearity between the diameter (or fluorescence intensity) of the fluorescence quenching ring and the mercury ion concentration allowed for the quantitative determination of Hg (II). The sensor is a step closer to real-world applications and has the ability to identify things quickly with an on-site triple signal readout …”

“…The sensor is a step closer to real-world applications and has the ability to identify things quickly with an on-site triple signal readout. 216 Nitrogen-doped carbon nanodots (N-CNDs) were produced from Auricularia auricula (L.ex Hook.) by Wenjing Chen et al using a one-step hydrothermal process.…”

Environmentally sustainable synthesis of whey-based carbon dots for ferric ion detection in human serum and water samples: evaluating the greenness of the method

“…They demonstrate uorescence when exposed to ultraviolet or visible light. [1][2][3][4] Moreover, they possess little toxicity, 5 outstanding photostability, 6 and high water solubility. 7 There are two main synthetic approaches for CDs: the topdown and bottom-up methods, which are categorized based on the relationship between sources and products.…”
