Naphthalimide-based Fluorescent Nanoprobes for the Detection of Saccharide

Abstract

Three kinds of fluorescent nano probes SN-A, SN-B and SN-C, based on photo-induced electron transfer mechanism, were synthesized for the detection of saccharide. 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 significant influence on the performance of the nanoprobes, however, the length of the linker affected the spectral response to a much less extent. The fluorescence intensity at 530 nm (I530) of SN-B exhibited good linear relationship with fructose/sorbitol concentration and was employed in the detection of fructose content in drinks.
