Tumors, inflammation and circulatory disorders locally disturb the body’s acid-base balance. These changes in pH value could be used for example to verify the success of cancer treatments.

Now a team has developed a pH sensor that renders pH values visible through magnetic resonance imaging (MRI) — in a non-invasive, radiation-free manner.
