Dynamic nuclear polarisation
Dynamic nuclear polarisation (DNP) is a technique used by scientists to get better pictures of molecules.
In a normal molecule, the nuclei (the small parts inside the molecule) all have the same types of "spins". DNP helps to make these spins more noticeable by increasing the amount of energy that they can hold.
The way this works is scientists use a very strong magnet to send out waves of energy that make the spins inside the molecule move faster. This means they all have the same amount of energy, which makes them stand out more in the picture.
This technique helps scientists to get clearer images of molecules and can help them understand how they work and what they are made of.
