Green and cost-effective fluorescent carbon nanoparticles for the selective and sensitive detection of iron (III) ions in aqueous solution: Mechanistic insights and cell line imaging studies

Nitrogen-doped carbon dots for sensitive detection of ferric ions and monohydrogen phosphate by the naked eye and imaging in living cells

“…The quenching efficiency [(F 0 -F)/F 0 ] reveals a good linear relationship (R 2 = 0.9993) with the concentration of Fe 3+ in a range of 0-65 μM, where F 0 and F are the fluorescence intensities of the N-CDs at 556 nm in the absence and presence of Fe 3+ , respectively (Fig.3b). The limit of detection is 0.85 μM based on S/N=3 method, which is much lower than the maximum concentration of Fe 3+ in drinking water (~5.357 μM) permitted by the US Environmental Protection Agency (EPA), 37 suggesting that the as-synthesized N-CDs could serve as a sensitive nanosensor for Fe 3+ detection.

A coumarin-containing Schiff base fluorescent probe with AIE effect for the copper(ii) ion

“…2B) using the equation. 46 It was deduced from the uorescence titration prole that the LOD of CTPE toward Cu 2+ ion reached 0.36 mM.…”

High-Yield Production of Water-soluble MoS₂ Quantum Dots for Fe³⁺ Detection and Cell Imaging

“…6a, only the addition of Fe (Fig. 6d), the detection limit (LOD) for Fe 3+ ions was measured to be 2.03 μM (3σ per slope) (R 2 = 0.9904), which met the limit of Fe 3+ in drinking water (5.357 μM) set by U. S. Environmental Protection Agency [40].…”
