Hyperpolarization in a benchtop DNP setup using polymers ? 🤔

Here's an update on HYPOP matrices in the #Hypflow polarizer !

Hyperpolarizing polymers (HYPOPs) are porous epoxy-amine polymers with covalently grafted nitroxide radicals. Their use in our HypFlow project aims to enable repeating multiple cycles of freeze-DNP-melt and liquid state analysis of a pure and undiluted sample. This work presents the first results of HYPOPs recorded in our 1 Tesla benchtop DNP polarizer operating at 77 Kelvin.
