| 英文摘要 | fluorescent organic nanoparticles (fons) based on carbohydrate polymers were prepared through one-pot hydrothermal treatment of starch in the presence of polyethyleneimine. these fons (named as pei-starch fons) were characterized by a series of techniques including uv vis absorption spectroscopy, fluorescent spectroscopy, fourier transform infrared spectroscopy, transmission electron microscopy and x-ray photoelectron spectroscopy. results showed that the size of pei-starch fons is 10-30 nm. the pei-starch fons exhibited high water dispersibility because of the existence of hydrophilic functional groups on their surface. after excited with different wavelength, pei-starch fons emitted strong and excitation-dependent fluorescence. to evaluate their potential for biomedical applications, biocompatibility and cell uptake behavior of pei-starch fons were further investigated. we demonstrated that pei-starch fons are biocompatible with cells and can be easily internalized by cells within 3 h. taken together, novel fons have been prepared via a simple and scalable hydrothermal method using starch and polyethyleneimine as precursors. these pei-starch fons showed excellent fluorescence properties, high water dispersibility and good biocompatibility, making them highly potential for various biomedical applications.
