Baumgarten develops magnetorelaxometry imaging of magnetic nanoparticles with OPMs and biomagnetic source analysis for biomedical sensing. This vapour-phase approach reaches femto-to-picotesla sensitivities complementary to NV-center diamond ensemble quantum sensors (DEER, nano-NMR, T1 relaxometry) that operate near the pT/sqrt(Hz) regime.
Middelmann develops OPM-based magnetorelaxometry imaging of magnetic nanoparticles, vector OPMs and OPM magnetomyography/MEG at PTB. This vapour-phase approach reaches femto-to-picotesla sensitivities complementary to NV-center diamond ensemble quantum sensors (DEER, nano-NMR, T1 relaxometry) that operate near the pT/sqrt(Hz) regime.
