【摘要】：β-HgS量子点因其具有可调谐的可见-近红外荧光和带间荧光而在光转换和荧光成像等多个领域有着广阔的应用前景。本文综述了β-HgS量子点的制备、性质及应用,重点梳理了β-HgS量子点在有机相和水相中的两大类共计五种制备方法,阐述了其不同于块状β-HgS的独特性质,总结了其在离子探测、细胞成像、活体成像、光转换器和荧光油墨等领域的最新应用。最后针对制约β-HgS量子点应用的主要问题(如应用于光转换器件中的转换效率和荧光量子产率不高、应用于生物荧光成像中的特异性识别能力不足和生物相容性较差等),提出了我们的解决方案:一方面,将β-HgS量子点自组装形成特定的纳米结构,以期提高其光转换效率和荧光量子产率;另一方面,通过将手性生物分子引入到β-HgS量子点表面来制备手性β-HgS量子点,以期增强其在体内和体外荧光成像中的特异性识别能力和改善其生物相容性。本文将为β-HgS量子点的发展提供新的思路。
[Abstract]:尾 -HgS quantum dots have broad application prospects in many fields such as optical conversion and fluorescence imaging due to their tunable visible-near infrared fluorescence and inter-band fluorescence. The preparation, properties and applications of 尾 -HgS quantum dots are reviewed in this paper. In this paper, five preparation methods of 尾 -HgS quantum dots in organic phase and water phase are reviewed, and their unique properties different from block 尾 -HgS are described, and their applications in ion detection, cell imaging and in vivo imaging are summarized. The latest applications of optical converters and fluorescent inks. Finally, the main problems that restrict the application of 尾 -HgS quantum dots (such as low conversion efficiency and low fluorescence quantum yield in optical converters) are discussed. In this paper, we put forward our solution: on the one hand, we self-assemble 尾 -HgS quantum dots to form specific nanostructures. On the other hand, chiral 尾 -HgS quantum dots were prepared by introducing chiral biomolecules into the surface of 尾 -HgS quantum dots. In order to enhance its specific recognition ability in vivo and in vitro fluorescence imaging and improve its biocompatibility, this paper will provide a new idea for the development of 尾 -HgS quantum dots.
