"Enhanced MRI relaxivity of aquated Gd3+ﾠions by carboxyphenylated water-dispersed graphene nanoribbons." <i>Nanoscale,</i> 6, (2014) Royal Society of Chemistry: 3059-3063. http://dx.doi.org/10.1039/C3NR06026H.https://hdl.handle.net/1911/88257The present study demonstrates that highly water-dispersed graphene nanoribbons dispersed by carboxyphenylated substituents and conjugated to aquated Gd3+ﾠions can serve as a high-performance contrast agent (CA) for applications inﾠT1- andﾠT2-weighted magnetic resonance imaging (MRI) with relaxivity (r1,2) values outperforming currently-available clinical CAs by up to 16 times forﾠr1ﾠand 21 times forﾠr2.engThis Open Access Article is licensed under aﾠCreative Commons Attribution-Non Commercial 3.0 Unported Licence.Journal articlehttp://dx.doi.org/10.1039/C3NR06026H
