Self‐assembled magnetic nanomaterials: Versatile theranostics nanoplatforms for cancer

Self‐assembled magnetic nanomaterials (MNMs) are a class of promising biomaterials possessing excellent physiochemical and biological characteristics, making them highly attractive in biomedical applications. A myriad of magnetic nanosystems can be created by using self‐assembly as a synthetic tool. Favorable nano‐bio interfacial properties are shown in these promising self‐assembled magnetic nanosystems, while still retaining their physical/chemical functionalities. This review aims to provide a systematical overview of the self‐assembled MNMs. In addition, this review highlights their implementations in cancer theranostics in detail. Overall, this review points out the direction for the application of self‐assembled MNMs in biomedicine, and presents how clinical oncology could benefit from the self‐assembled nanotechnology.
