| Popis: | Multimodal imaging nanoparticles that integrate different imaging modalities into one system could provide complementary and detailed imaging information to satisfy the request of precision medicine. However, most multimodal nanoparticles suffer from multistep synthesis and complicated compositions, which hinder their practical application in biomedical research. Therefore, development of a facile method to prepare a single-nanoparticle contrast agent to achieve multimodal imaging is of significance. In this paper, hyaluronic-acid-modified manganese tungstate nanoparticles (HA-MnWO4 NPs) were successfully synthesized via a facile one-step hydrothermal procedure for efficient T1/T2-weighted MR and CT trimodal imaging in vivo. In the single-nanoparticle, manganese (Mn) with five unpaired electrons offers strong relaxation for MR imaging, while tungsten (W) with high atomic number provides high X-ray attenuation coefficient for CT imaging. Furthermore, HA-template synthesis endows the HA-MnWO4 nanoparticle w... |
