However, a better understanding of EV in vivo behavior is hampered by the limitations of current imaging tools. In addition, chemical labels present the risk of altering the EV membrane features and, thus, in vivo behavior. 19F-MRI is a safe bioimaging technique providing selective images of exogenous probes. Here, we present the first example of fluorinated EVs containing PERFECTA, a branched molecule with 36 magnetically equivalent 19F atoms. A PERFECTA emulsion is given to the cells, and PERFECTA-containing EVs are naturally produced. PERFECTA-EVs maintain the physicochemical features, morphology, and biological fingerprint as native EVs but exhibit an intense 19F-NMR signal and excellent 19F relaxation times. In vivo 19F-MRI and tumor-targeting capabilities of stem cell-derived PERFECTA-EVs are also proved. We propose PERFECTA-EVs as promising biohybrids for imaging biodistribution and delivery of EVs throughout the body. 000125861 536__ $$9info:eu-repo/grantAgreement/ES/ISCIII/CIBER-BBN$$9info:eu-repo/grantAgreement/ES/MEC/FPU15-03419$$9info:eu-repo/grantAgreement/ES/MINECO/Consolider-Ingenio2010 000125861 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000125861 590__ $$a8.5$$b2023 000125861 592__ $$a2.058$$b2023 000125861 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b28 / 141 = 0.199$$c2023$$dQ1$$eT1 000125861 593__ $$aMaterials Science (miscellaneous)$$c2023$$dQ1 000125861 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b68 / 439 = 0.155$$c2023$$dQ1$$eT1 000125861 593__ $$aNanoscience and Nanotechnology$$c2023$$dQ1 000125861 593__ $$aMedicine (miscellaneous)$$c2023$$dQ1 000125861 594__ $$a16.0$$b2023 000125861 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000125861 700__ $$aAyaz, Nazeeha 000125861 700__ $$0(orcid)0000-0002-6873-5244$$aSebastian, Victor$$uUniversidad de Zaragoza 000125861 700__ $$aChirizzi, Cristina 000125861 700__ $$aEncinas-Gimenez, Miguel$$uUniversidad de Zaragoza 000125861 700__ $$aNeri, Giulia 000125861 700__ $$aChaabane, Linda 000125861 700__ $$0(orcid)0000-0002-2053-9842$$aLuján, Lluís$$uUniversidad de Zaragoza 000125861 700__ $$aMartin-Duque, Pilar 000125861 700__ $$aMetrangolo, Pierangelo 000125861 700__ $$0(orcid)0000-0002-8701-9745$$aSantamaría, Jesús$$uUniversidad de Zaragoza 000125861 700__ $$aBaldelli Bombelli, Francesca 000125861 7102_ $$11009$$2773$$aUniversidad de Zaragoza$$bDpto.
