此系列产品为羧基功能化上转换纳米颗粒,材料组成为NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu),最佳激发波长为975 nm。敏化离子为Yb3+,激活离子为Er3+或Tm3+。通过调节各离子掺杂浓度,产品在特定波长的发光已得到优化。表面包覆的二氧化硅或PEG使纳米颗粒具有良好的亲水性,可以直接分散在水介质中。产品粒径均一,发光量子效率高,光稳定性好。该系列产品可与生物分子共价连接,用于荧光成像、生物检测、免疫分析,以及抗癌药物和生物分子的光控远程释放等。
This series of products are carboxyl functionalized up-conversion nanoparticles. The material composition is NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu), and the best excitation wavelength is 975 nm. The sensitizing ion is Yb3+, and the activating ion is Er3+ or Tm3+. By adjusting the doping concentration of each ion, the luminescence of the product at a specific wavelength has been optimized. The surface-coated silica or PEG makes the nanoparticles have good hydrophilicity and can be directly dispersed in aqueous media. The product has uniform particle size, high luminous quantum efficiency and good light stability.
After proper surface modification and functionalization, the products can be used for fluorescence imaging, biodetection, immunity analysis and photoactivation of anti-cancer drugs and biomolecules.
