Abstract: In this work, copper-doped carbon nanoparticles with emission in a wide spectral range and the ability to change the relaxation times of water protons during magnetic resonance imaging were fabricated. A high relaxivity value r1 = 0.92 mM$^{-1}$ $\cdot$ s$^{-1}$ was achieved, which is the highest value of r1 for copper nanoparticles, to our knowledge. The suggested carbon nanoparticles are promising two-modal nanoprobes for bioimaging.

Keywords: carbon nanoparticles, long-wavelength photoluminescence, magnetic resonance imaging, contrast agents.
