Quality control procedures were carried out using thin layer radiochromatography. The labeling yield of radiolabeled polymer was found to be about 100%. Then, stability and lipophilicity were determined. The lipophilicity of 99mTc labeled Fe3O4 graft-Lys-poly(HEMA) was found to be 3.77. The serum stability experiments demonstrated that approximately 100% of radiolabeled polymer existed as an intact complex in the rat serum within 240 min. Biodistribution of radiolabeled magnetic graft-Lys-poly(HEMA) was performed on female Albino Wistar rats by scintigraphy and biodistribution studies. High uptake was seen in the stomach, the pancreas, brain, ovarian, intestines and the breast. © 2019 Elsevier LtdEnglishAnimalsDrug StabilityFemaleMagnetite NanoparticlesMaleMicroscopy, Electron, ScanningOrganotechnetium CompoundsPolyhydroxyethyl MethacrylatePolymersRadiopharmaceuticalsRatsRats, WistarTissue DistributionAmino acidsChromatographyIron oxidesMagnetiteNanoparticlesNuclear medicinePolymersRatsTechnetium compoundspolymacontechnetium 99mmagnetite nanoparticlepolymaconpolymerradiopharmaceutical agenttechnetium complexBiodistributionsControl proceduresGrafted polymersHEMAl-LysineLipophilicityRadiochromatographySerum stabilityanimal experimentanimal tissueArticlebrainbreastcontrolled studydrug blood leveldrug distributiondrug stabilitydrug synthesisdrug tissue levelfemaleintestineisotope labelinglipophilicitymalenonhumannuclear pharmacyovarypancreaspriority journalquality control proceduresratscintigraphystomachWistar ratanimalchemistryscanning electron microscopysynthesistissue distributionultrastructureGrafting (chemical)Article10.1016/j.apradiso.2019.108872
