摘要

以长链希夫碱配体为原料合成了尺寸为1.8 nm × 2.0 nm × 2.0 nm的12金属Zn(II)-Nd（III）簇1。采用I545 nm/I1060 nm = A·[Neo]2 + B·[Neo] + C. 1定量测定胎牛血清（FCS）和尿液中Neo浓度，回收率分别为98.57% ~ 103.82%和99.25% ~ 103.50%，相对标准偏差（rsd）分别为7.89% ~ 9.46%和1.85% ~ 4.16%。FCS和尿液中1 ~ Neo的检出限分别为0.034和0.021 μmol/L。

Construction of a 12-metal Zn(II)-Nd(III) nanocluster for ratiometric fluorescence detection of inflammatory marker neopterin

A 12-metal Zn(II)-Nd(III) cluster 1 (sizes: 1.8 nm × 2.0 nm × 2.0 nm) was synthesized from a long-chain type Schiff base ligand. It displays ratiometric fluorescence response to neopterin (Neo) with high selectivity and sensitivity, which can be expressed by the equation I_{545 nm}/I_{1060 nm} = A·[Neo]² + B·[Neo] + C. 1 is used to quantitatively test Neo concentrations in fetal calf serum (FCS) and urine, and the recovery ranges are 98.57%–103.82% and 99.25%–103.50%, respectively, while the relative standard deviations (RSDs) are 7.89%–9.46% and 1.85%–4.16%, respectively. The limits of detection of 1 to Neo in FCS and urine are 0.034 and 0.021 μmol/L, respectively.

期刊介绍： The Journal of Rare Earths reports studies on the 17 rare earth elements. It is a unique English-language learned journal that publishes works on various aspects of basic theory and applied science in the field of rare earths (RE). The journal accepts original high-quality original research papers and review articles with inventive content, and complete experimental data. It represents high academic standards and new progress in the RE field. Due to the advantage of abundant RE resources of China, the research on RE develops very actively, and papers on the latest progress in this field emerge every year. It is not only an important resource in which technicians publish and obtain their latest research results on RE, but also an important way of reflecting the updated progress in RE research field. The Journal of Rare Earths covers all research and application of RE rare earths including spectroscopy, luminescence and phosphors, rare earth catalysis, magnetism and magnetic materials, advanced rare earth materials, RE chemistry & hydrometallurgy, RE metallography & pyrometallurgy, RE new materials, RE solid state physics & solid state chemistry, rare earth applications, RE analysis & test, RE geology & ore dressing, etc.
