Manganese-Doped Carbon Dots for Magnetic Resonance/Optical Dual-Modal Imaging of Tiny Brain Glioma
Brain gliomas are
life-threatening diseases with low survival rates.
Early detection and accurate intraoperative location of brain gliomas
is vital to improving the prognosis. Herein, we synthesized manganese
(Mn)-doped carbon dots (CDs) as magnetic resonance (MR)/optical dual-modal
imaging nanoprobes by a one-pot green microwave-assisted route. These
ultra-small-sized Mn-doped CDs possess distinct excitation-dependent
photoluminescent emissions, high <i>r</i><sub>1</sub> relaxivity,
and low cytotoxicity. The in vivo MR imaging and ex vivo optical imaging
of mouse brain with tiny glioma demonstrate that the Mn-doped CDs
could lead to an enhanced MR <i>T</i><sub>1</sub> contrast
effect in the tiny brain glioma region, disclosing the great promise
of these Mn-doped CDs as MR/optical dual-modal imaging nanoprobes
for detection and intraoperative location of tiny brain gliomas
