Özet

The present study demonstrates that highly water-dispersed graphene nanoribbons dispersed by carboxyphenylated substituents and conjugated to aquated Gd3+ ions can serve as a high-performance contrast agent (CA) for applications in T-1- and T-2-weighted magnetic resonance imaging (MRI) with relaxivity (r(1,2)) values outperforming currently-available clinical CAs by up to 16 times for r(1) and 21 times for r(2).
