Highly Selective and Sensitive Sensing of Toxic Mercury Ions Utilizing Carbon Quantum Dot-Modified Glassy Carbon Electrode

Electrophilicity modulated targeted luminescence of MOF-coated cotton composite for dual analyte detection in aqueous medium

“…Hyperconcentration of mercury affects the heart, kidney, nervous system, and liver. 4,5 Therefore, USA EPA has set the highest concentration limit of mercury in water as 2 ppb. Hence, the selective detection of mercury below the limits set by USA EPA is highly required.…”

Fluorescent Carbon Dots from Snake Plant for Applications as Probe for Optical and Electrochemical Sensing of Hg2+ and Fe3+ and Bio‐Imaging Agent

“…The optical properties of CDs were also studied, the UV‐vis spectrum recorded in aqueous medium is shown in Figure 4a. It exhibited a band in the UV region at 278 nm, which is due to n‐$${\pi }$$ * transition of C=O and conjugated C=C [35,36] . These CDs are highly fluorescent, its fluorescence spectrum recorded upon excitation at 340 nm is shown in Figure 4a, which exhibited a strong band at 425 nm.…”

[35,36] These CDs are highly fluorescent, its fluorescence spectrum recorded upon excitation at 340 nm is shown in Figure 4a, which exhibited a strong band at 425 nm. The similarity in the CDs prepared in each batch and its stability before using it for any study was checked with the aid of UV-Vis and fluorescence spectral studies conducted under same experimental conditions.…”

Portable sensing methods based on carbon dots for food analysis

“…It became an issue that how to distinguish between CU and MY (Shereema et al, 2018) Excessive Hg 2+ levels in food can cause harm to the human body. Barvin et al (2019) dropped CDs solution onto GCE to prepare electrodes for detecting Hg 2+ . The LOD for Hg 2+ is 2.5 nM (2.5-350 nM).…”
