We report here a nanospherical polymer consisting of methacrylic acid and N,N′-methylenebisacrylamide, which works as a metal-free magnetic resonance imaging (MRI) sensor for pH. The nanospherical polymer gave a lower signal T2-weighted MRI image with decreasing pH. In contrast, it had little effect on the T1-weighted MRI image.
