Fig. 5From: Carboxylated superparamagnetic Fe3O4 nanoparticles modified with 3-amino propanol and their application in magnetic resonance tumor imagingApplication of 3-amino propanol modified superparamagnetic Fe3O4 nanoparticles in magnetic resonance tumor imaging. A Tumor imaging was investigated through MRI. B The tumor brightness was analyzed.
