Modification of functional polymer nanoparticles with Oxazolidine (OXOH) can led to development of a new category of advanced materials that have potential applications such as anticounterfeiting inks, chemosensors, drug-delivery systems and bioimaging. In this study, a new type of amide functionalized copolymer nanoparticles has been synthesized by emulsion copolymerization of methylmathacrylate (MMA) and methacrylamide (MAAm). The photoluminescent copolymer nanoparticles (PLCNPs) were prepared by physical modification of amide functionalized copolymer nanoparticles with OXOH. In addition, the obtained polymer nanoparticles were characterized by 1HNMR analyses, and optical properties were studied by fluorescent (excited at 420 nm) and UV-Vis specteroscopieis. Finally, prepared photoluminescent nanoparticles were used for development of flourescent papers and printing of fluorescent security tags on confidential documents.
