Researchers from Tokyo Institute of Technology, the Innovation Center of Nanomedicine, and the Japan Agency for Quantum and Radiological Science and Technology have come up with a new nanoparticle that can help spot tiny sites of tumor malignancy under magnetic resonance imaging (MRI). While MRI contrast agents for detecting tumors have been created in the past, ones that amplify the MR signal when in low pH environments, as within malignant tissue, have not existed.
