(13)C-engineered carbon quantum dots ((13)C-QDs) were used as magnetic resonance (MR) and fluorescence dual-response probe. The enhanced (13)C-MR signal was observed at 171 ppm from carboxylic and carboxyl carbons in (13)C-QDs with 160-fold improvement on signal-to-noise ratio even when no hyperpolarization was applied, whereas the intrinsic fluorescence of… CONTINUE READING
