a UV-vis absorbance of Mn@CCs. Inset: Photograph of the purified Mn@CCs under daylight. b Photoluminescent spectra of Mn@CCs. c The r1 relaxivities of Mn@CCs investigated in a 1.5 T, 7.0 T, and 9.4 T MRI system. d The r1 relaxivities of glucose-Mn investigated in a 1.5 T, 7.0 T, and 9.4 T MRI system. e The r1 relaxivities of Magnevist (Gd-DTPA) investigated in a 1.5 T, 7.0 T, and 9.4 T MRI system. f Comparison of r1 relaxivities of Mn@CCs, glucose-Mn, and Gd-DTPA.
