Pentacene Dimers Boost Quantum Sensing Towards Single-Proton Detection
Researchers at the Institute of Translational Medicine have shown that pentacene dimers, created via singlet fission, provide a 30% larger interaction cross‑section than traditional pentacene monomers for detecting small ensembles of nuclear spins.

The study also demonstrates that sensitivity scales with the number of sensing pulses and is optimized in low‑magnetic‑field environments. These findings lay a theoretical foundation for high‑spin quantum probes in nanoscale magnetic resonance applications.
