Taking MRI technology down to micrometer scales

Millions of magnetic resonance imaging (MRI) scans are performed each year to diagnose health conditions and perform biomedical research. The different tissues in our bodies react to magnetic fields in varied ways, allowing ...

New metamaterial-enhanced MRI technique tested on humans

Scientists from the Netherlands and Russia have designed and tested a new metasurface-based technology for enhancing the local sensitivity of MRI scanners on humans for the first time. The metasurface consists of thin resonant ...

New biosensor zymonic acid shows changes in pH value

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. Up to now, however, there has been ...
