Three kinds of fluorescent nano probes SN-A, SN-B and SN-C, based on the photo-induced electron transfer mechanism, were synthesized for the detection of saccharides, in which small fluorescent probes with 1,8-naphthalimide as the fluorophore and phenylboronic acid as the receptor were covalently bound to SiO2 nanoparticles. The fluorescent nano particles were characterized by TEM, IR, UV-Vis and fluorescence spectra. The results showed that the particle diameter exerted a significant influence on the performance of the nanoprobes; however, the length of the linker affected the spectral response to a much lesser extent. The fluorescence intensity at 530 nm (I530) of SN-B exhibited a good linear relationship with the fructose/sorbitol concentration and was employed in the detection of the fructose content in drinks.

基于萘二甲酰亚胺的荧光纳米探针,用于检测糖类

基于光致电子转移机理,合成了三种荧光纳米探针SN-A,SN-B和SN-C用于糖类的检测,其中以1,8-萘二甲酰亚胺为荧光团的小型荧光探针苯基硼酸作为受体与SiO 2纳米颗粒共价结合。通过TEM,IR,UV-Vis和荧光光谱对荧光纳米颗粒进行表征。结果表明,粒径对纳米探针的性能影响很大。然而,接头的长度对光谱响应的影响程度要小得多。530 nm(I 530的荧光强度SN-B与果糖/山梨糖醇浓度呈良好的线性关系,被用于饮料中果糖含量的检测。
