The suitability of these PEG derivatives to be conjugated to nanomaterials was shown by pegylation of ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles (NPs), followed by functionalization with small peptide ligands for biomedical applications.Functionalized nanoparticlesHeterotelechelic PEG oligomerPegylationSelective monoreductionCancer cells targetingUSPIO NPsConvenient synthesis of heterobifunctional poly(ethylene glycol) suitable for the functionalization of iron oxide nanoparticles for biomedical applicationstext::journal::journal article::research article
