| 英文摘要 | c-13-engineered carbon quantum dots (c-13-qds) were used as magnetic resonance (mr) and fluorescence dual-response probe. the enhanced c-13-mr signal was observed at 171 ppm from carboxylic and carboxyl carbons in c-13-qds with 160-fold improvement on signal-to-noise ratio even when no hyperpolarization was applied, whereas the intrinsic fluorescence of c-qds was still maintained. the stable mr and fluorescence dual-response was successfully used for long-term observation of zebrafish embryonic development. cross-validation between mr and fluorescence confirmed the distribution of c-13-qd in zebrafish. c-13-mr provides specific information about the presence, magnitude, and progression of 13c-qds by defining mr intensity, whereas fluorescence reveals the location of c-13-qd5 with its high sensitivity. c-13-mr and fluorescence was simultaneously observed within c-13-qds, and this work may expand the applications of isotope-engineered nanomaterials. |
