Fortunately, rapidly developing in the past decade, nanotechnology has become one of the most promising technologies for cancer theranostics. Recent studies have demonstrated that transition metal nanoparticles, especially manganese nanoparticles (Mn-NPs), display great potential for application in various oncology fields due to their unique fundamental properties. Although global scientists have developed a variety of new Mn-NPs and have proved their preponderance in cancer diagnosis and treatment, Mn-NPs are still not approved for clinical use. In this paper, the research progress of Mn-NPs in the fields of cancer diagnosis and therapy in recent years is reviewed. Besides, the future prospect and challenges of Mn-NPs are discussed to explore wider applications of Mn-NPs in clinic. Here, we hope that this review will show a better overall understanding of Mn-NPs and provide guidance for their design in clinical applications for cancer.
