Abstract:

Magnetic resonance imaging(MRI) is a powerful non-invasive biomedical diagnostic technique. Clinically, MRI requires contrast agents to improve imaging quality, thereby improving the diagnosis accuracy. Due to the superior signal amplification ability and biocompatibility, self-assembled peptide probes can be loaded with specific MRI molecules to achieve tumor targeting and enriching through the enzyme responsive self-assembly process. Thus, self-assembled peptide probes can enhance the MRI signal of tumor lesions, thereby further improving the accuracy and sensitivity of MRI. This review summarizes the recent progress of self-assembled peptide probes under different MRI modalities( 1H MRI, 19F MRI, dual nuclei MRI), and highlights their potential for cancer diagnosis.

Key words: Self-assembled polypeptide, Enzyme responsive MRI probe, 1H MRI, 19F MRI, Tumor imaging
