A boron‐doped graphene quantum dot (B‐GQD) as a metal‐free multimodal contrast agent (CA) for safe magnetic resonance imaging and fluorescence imaging is reported. In vivo T 1 ‐weighted magnetic resonance images show that B‐GQDs induce significant contrast enhancement on the heart, liver, spleen, and kidney, and sustain for more than 1 h, about 10 times longer than Gd‐based CAs currently used in clinic.
