Abstract
Researchers reported the development of metal-free boron-doped graphene quantum dots (B-GODs) as a safe contrast agent for MRI. This magnetic property is produced by introducing both vacancies and elemental boron molecules as the substitutional defect. The B-GQDs were synthesized at 200 °C using 4-vinylphenylboronic acid (VPBA) and with boric acid as the precursor. defects in the GQD framework provide active sites for boron doping by decomposition of VPBA and boric acid, thus leading to the formation of B-GQDs by a nuclear burst at the supersaturation point.
