  1. 量子点的前沿应用（混合多功能） 2012.9 郑昊

  2. CdTe与Fe3O4

  3. 疏水量子点合成磁性复合纳米粒子 Color-tunable magnetic and luminescent hybrid nanoparticles[1]

  4. 水溶性量子点合成磁性纳米粒子 Synthesis and characterization of magnetic and luminescent Fe3O4/CdTenanocomposites using aspartic acid as linker[2] Synthesis and characteristics of multifunctional Fe3O4-SiO2-CdS magnetic-fluorescent nanocomposites[3] Bifunctional luminescent superparamagneticnanocomposites of CdSe/CdS-Fe3O4 synthesized via a facile method[4]

  5. The double-effect mechanism between Fe3O4 nanoparticles and MSA-capped CdTeQDs[5] MSA包裹的CdTe量子点中加入少量Fe3O4 小粒径荧光猝灭 大粒径荧光加强 加强程度和激发波长，Fe3O4浓度有关

  6. a为560绿光CdTe.b为660红光CdTe

  7. 420nm激发波长 570nm激发波长

  8. 重要方向： 既具有量子点的荧光特性而且可以用于强外部磁场，很新颖，值得探索，在生物分离，生物标记以及靶向给药等方面有着广阔的应用前景。目前相关应用的文献都很新。

  9. 应用：Fluorometric method for the determination of hydrogen peroxide and glucose with Fe3O4 as catalyst[6] H2O2与CdTe,Fe3O4体系荧光淬灭

  10. 葡萄糖浓度与混合纳米材料的荧光淬灭

  11. 小结： 这篇文献是11年的，早于先前文献，有些问题值得讨论和延伸，从中得到了一些经验。 思路： 先用葡萄糖氧化酶或者酚氧化酶实验，然后换别的酶系统实验。

  12. Layer-by-Layer Assembled Fe3O4@C@CdTe Core/Shell Microspheres as Separable Luminescent Probe for Sensitive Sensing of Cu2+ Ions[7]

  13. 不同层数

  14. Magnetic beads-based electrochemiluminescenceimmunosensor for determination of cancer markers using quantum dot functionalized PtRualloys as labels[8] PtRu合金作为固定量子点和抗体的载体，用于增幅信号，放大了4.67倍相比于只用量子点 最主要的单克隆抗体被固定在壳聚糖包裹的Fe3O4上，因其磁性，单克隆抗体很容易固定在氧化铟锡玻璃上

  15. 免疫传感器制备原理

  16. 想法： 可以对这个原理和实验进行优化：不用壳聚糖包裹的Fe3O4而用量子点包裹的Fe3O4可以减少实验流程，简化实验

  17. 不同浓度抗原溶液的光谱强度图

  18. Magnetic-room temperature phosphorescent multifunctional nanocompositesas chemosensor for detection and photo-driven enzyme mimetics for degradation of 2,4,6-trinitrotoluene[9] Novel Magnetic Fe3O4@CdSe Composite Quantum Dot-Based Electrochemiluminescence Detection of Thrombin by a Multiple DNA Cycle Amplification Strategy[10]

  19. CdTe与氧化石墨烯GO

  20. Dual-emission of a fluorescent graphene oxide–quantum dot nanohybrid for sensitive and selective visual sensor applications based on ratiometric fluorescence[11] 不同荧光石墨烯浓度下双峰

  21. Fe2+浓度影响 加入H2O2后Fe2+影响

  22. 小结：这个荧光比率测定方法也比较新颖。可以尝试其它金属离子，或者酶催化反应系统小结：这个荧光比率测定方法也比较新颖。可以尝试其它金属离子，或者酶催化反应系统

  23. 此外： CdTe与SiO2相关领域也有很大空间 与太阳能电池相关 共振瑞利散射代替荧光法 谢谢
