Luminescence tunable fluorescent organic nanoparticles from polyethyleneimine and maltose: facile preparation and bioimaging applications

Novel fluorescent organic nanoparticles (FONs) were facilely prepared via hydrothermal treatment of maltose and polyethyleneimine in water. These FONs exhibited suitable size and size distribution, high water dispersibility, excellent biocompatibility and tunable luminescence, making them highly potential for biological imaging applications.
