Abstract

Self-assembling conjugated polymer nanoparticles containing PVKand PLGA-PEG as a matrix polymer were doped with both a luminescentrare-earth complex and magnetic nanoparticles (SPIONs),giving rise to materials that are both luminescent and magnetic.Nanoparticle sizes ranged from 80–110 nm without SPIONs andshowed an increase in size (200–1000 nm) with additional SPIONcontent (11–54%). Quantum yields (QYs) of 24% and 18% weremeasured for systems without and with 11% SPIONs, respectively.Optical properties were stable and suitable for biological imagingapplications.
