Carbon Dots Based Dual-Emission Silica Nanoparticles as a Ratiometric Nanosensor for Cu2+
Abstract
A simple and effective strategy for designing ratiometric fluorescent nanosensor has been described in this work. A carbon dots (CDs) based dual-emission nanosensor for Cu(2+) detection was prepared by coating CDs on the surface of Rhodamine B-doped silica nanoparticles. The fluorescent CDs were synthesized using N-(β-aminoethyl)-γ-aminopropyl methyldimethoxysilane (AEAPMS) as the main raw material, so that the residual ethylenediamine groups and methoxysilane groups on the surface of CDs can serve as the Cu(2+) recognition sites and the silylation reaction groups. The obtained nanosensor showed characteristic fluorescence emissions of Rhodamine B (red) and CDs (blue) under a single excitation wavelength. Upon binding to Cu(2+), only the fluorescence of CDs was quenched, resulting in the ratiometric fluorescence response of the dual-emission silica nanoparticles. This ratiometric nanosensor exhibited good selectivity to Cu(2+) over other substances, such as metal ions, amino acids, proteins, and vitamin C. The ratio of F467/F585 linearly decreased with the increasing of Cu(2+) concentration in the range of 0 to 3 × 10(-6) M, a detection limit as low as 35.2 nM was achieved. Additionally, this nanosensor was successfully applied for the ratiometric fluorescence imaging of Cu(2+) in cells and determination of Cu(2+) in real tap water.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
