University of Tokyo Dec 4 2025 Magnetic resonance imaging (MRI) is invaluable in the medical world. But despite all the good it does, there is room for improvement. One way to enhance the sensitivity of MRI is called dynamic nuclear polarization (DNP), where target molecules for imaging are modified so they form clearer images when scanned with an MRI machine. But this technique requires some special crystalline materials mixed with polarizing agents which are difficult to create. For the first
