摘要

碳量子点作为光功能组分和纳米载体用于构筑磁共振-荧光双模态分子探针的研究才刚刚开始.本文首次以兼作Gd

)

可用作磁共振-荧光双模态分子影像探针.

Abstract

The study of carbon quantum dots used as either photoluminescence functional components or nano carriers for magnetic resonance-fluorescence multimodal molecular imaging probe is just beginning. In the paper

the gadopentetate monomeglumine was used as a precursor which provides simultaneously carbon sources and Gd

sources. The influences of pyrolysis temperature

holding time and heating rate on the carbonization degree of the precursor

the quantum yield and the Gd

content of the products were studied. When the precursor was pyrolized under reasonable condition (the pyrolysis temperature was not higher than 350 ℃)

chelates dopped carbon quantum dots were facilely prepared. The carbon quantum dots not only possessing high luminous power (quantum yield ~7.6%)

but also showing good magnetic resonance response (longitudinal relaxation rate ~6.5 mmol

-1

) can be used as a magnetic resonance/fluorescence multimodal molecular imaging probe.
