Spherical superparamagnetic iron oxide nanoparticles have been developed as T2-negative contrast agents for magnetic resonance imaging in clinical use because of their biocompatibility and ease of synthesis; however, they exhibit relatively low transverse relaxivity. Here we report a new strategy to achieve high transverse relaxivity by controlling the(More)
High-performance magnetic resonance imaging (MRI) contrast agents and novel contrast enhancement strategies are urgently needed for sensitive and accurate diagnosis. Here we report a strategy to construct a new T1 contrast agent based on the Solomon-Bloembergen-Morgan (SBM) theory. We loaded the ultrasmall gadolinium oxide nanoparticles into worm-like(More)
