Abstract
The abnormal Fe3+ level is known to cause various diseases, such as heart failure, liver damage and neurodegeneration. In situ probing Fe3+ in living cells or organisms is highly desired for both biological research and medical diagnostics. Herein, hybrid nanocomposites NaEuF4@TCPP were constructed by the assembly of an aggregation-induced emission luminogen (AIEgen) TCPP and NaEuF4 nanocrystals (NCs). The anchored TCPP on the surface of NaEuF4 NCs can reduce rotational relaxation of the excited state and efficiently transfer the energy to the Eu3+ ions with minimized nonradiative energy loss. Consequently, the prepared NaEuF4@TCPP nanoparticles (NPs) exhibited an intense red emission with a 103-fold enhancement relative to that in NaEuF4 NCs under 365 nm excitation. A selectively quenching response to Fe3+ ions for the NaEuF4@TCPP NPs makes them luminescent probes for sensitive detection of Fe3+ ions with a low detection limit of 340 nM. Moreover, the luminescence of NaEuF4@TCPP NPs could be recovered by the addition of iron chelators. Benefiting from their good biocompatibility and stability in living cells, together with the characteristic of the reversible luminescence response, the lipo-coated NaEuF4@TCPP probes were successfully applied for real-time monitoring of Fe3+ ions in living HeLa cells. These results are expected to motivate the exploration of AIE-based lanthanide probes for sensing and biomedical applications.

Application of Deep Eutectic Solvent Modified Cotton as a Sorbent for Online Solid-Phase Extraction and Determination of Trace Amounts of Copper and Nickel in Water and Biological Samples. Biol Trace Elem Res 2017; 176:207-215. [PMID: 27507416 DOI: 10.1007/s12011-016-0814-0] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2016] [Accepted: 07/29/2016] [Indexed: 11/26/2022]
Abstract
Deep eutectic solvent (DES) was used as the extractant to improve the extraction properties of cotton. DES of choline chloride-urea (ChCl-urea) was prepared and immobilized on the surface of cotton fibers. The resulting sorbent was packed on a microcolumn, and a flow injection flame atomic absorption spectrometry was designed for the online separation and determination of trace amounts of copper and nickel. Various parameters affecting the extraction recovery of analytes such as pH, sample volume, sample loading rate, nature, volume, concentration, and flow rate of eluent were investigated and optimized. Under the optimum conditions, the method showed good linearity in the concentration range of 0.25-50.0 and 4.0-125.0 μg L-1 with the coefficient of determination (r 2) of 0.9991 and 0.9990 for copper and nickel, respectively. The method was very sensitive with the detection limits (defined as 3Sb/m) of 0.05 and 0.60 μg L-1 for Cu and Ni, respectively. It was successfully applied for the determination of Cu and Ni in water and biological samples. The accuracy of the method was evaluated through the recovery experiments and independent analysis by electrothermal atomic absorption spectrometry.
