Besides the enhanced uptake due to specific interactions, the surfaceligands can be utilized for radiolabeling applications for bimodal imaging ensured by positron emission topography (PET) and magnetic resonance imaging (MRI) functions in one source. Herein, we describethe surface functionalization of magnetite (Fe3O4) with folic acid as a target vector. Additionally, the magnetic nanocarriers were conjugated with appropriate ligands for subsequent copper-catalyzed azide–alkyne cycloaddition or carbodiimide coupling reactions to successfully achieve radiolabeling with the PET-emitter 18F. The phase composition (XRD) and size analysis (TEM) confirmed the formation of Fe3O4nanoparticles (6.82 nm ± 0.52 nm). The quantification of various surface functionalities was performed by Fourier-transform infrared spectroscopy (FT-IR) and ultraviolet-visible microscopy (UV-Vis). An innovativemagnetic-HPLC method was developed in this work for the determination of the radiochemical yield of the 18F-labeled NPs. The as-prepared Fe3O4 particles demonstrated high radiochemical yields andshowed high cellular uptake in a folate receptor overexpressing MCF-7 cell line, validating bimodalimaging chemical design and a magnetic HPLC system. This novel approach, combining folic acidcappedFe3O4 nanocarriers as a targeting vector with 18F labeling, is promising to apply this probe forbimodal PET/MR-studies. 000894976 536__ $$0G:(DE-HGF)POF4-5253$$a5253 - Neuroimaging (POF4-525)$$cPOF4-525$$fPOF IV$$x0 000894976 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000894976 7001_ $$0P:(DE-HGF)0$$aRenner, Alexander M.$$b1 000894976 7001_ $$0P:(DE-HGF)0$$aIlyas, Shaista$$b2 000894976 7001_ $$0P:(DE-HGF)0$$aLê, Khan$$b3 000894976 7001_ $$0P:(DE-Juel1)176549$$aGuliyev, Mehrab$$b4 000894976 7001_ $$0P:(DE-Juel1)169356$$aKrapf, Philipp$$b5 000894976 7001_ $$0P:(DE-Juel1)166419$$aNeumaier, Bernd$$b6 000894976 7001_ $$0P:(DE-HGF)0$$aMathur, Sanjay$$b7$$eCorresponding author 000894976 773__ $$0PERI:(DE-600)2693928-9$$a10.1039/D1BM00616A$$gVol. 9, no. 13, p. 4717 - 4727$$n13$$p4717 - 4727$$tBiomaterials science$$v9$$x2047-4849$$y2021 000894976 8564_ $$uhttps://juser.fz-juelich.de/record/894976/files/Autorenversion.pdf$$yOpenAccess 000894976 8564_ $$uhttps://juser.fz-juelich.de/record/894976/files/d1bm00616a-1.pdf$$yOpenAccess 000894976 909CO $$ooai:juser.fz-juelich.de:894976$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000894976 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)169356$$aForschungszentrum Jülich$$b5$$kFZJ 000894976 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)166419$$aForschungszentrum Jülich$$b6$$kFZJ 000894976 9131_ $$0G:(DE-HGF)POF4-525$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5253$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vDecoding Brain Organization and Dysfunction$$x0 000894976 9141_ $$y2021 000894976 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2021-02-04 000894976 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2021-02-04 000894976 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2021-02-04 000894976 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2021-02-04 000894976 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bBIOMATER SCI-UK : 2019$$d2021-02-04 000894976 915__ $$0LIC:(DE-HGF)CCBYNC3$$2HGFVOC$$aCreative Commons Attribution-NonCommercial CC BY-NC 3.0 000894976 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-02-04 000894976 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2021-02-04 000894976 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000894976 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bBIOMATER SCI-UK : 2019$$d2021-02-04 000894976 915__ $$0StatID:(DE-HGF)0430$$2StatID$$aNational-Konsortium$$d2021-02-04$$wger 000894976 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-02-04 000894976 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2021-02-04 000894976 920__ $$lyes 000894976 9201_ $$0I:(DE-Juel1)INM-5-20090406$$kINM-5$$lNuklearchemie$$x0 000894976 980__ $$ajournal 000894976 980__ $$aVDB 000894976 980__ $$aUNRESTRICTED 000894976 980__ $$aI:(DE-Juel1)INM-5-20090406 000894976 9801_ $$aFullTexts
