  author={Hiraku Toida and Koji Sakai and Tetsuhiko F. Teshima and Masahiro Hori and Kosuke Kakuyanagi and Imran Mahboob and Yukinori Ono and Shiro L. Saito},
We demonstrate magnetometry of cultured neurons on a polymeric film using a superconducting flux qubit that works as a sensitive magnetometer in a microscale area. The neurons are cultured in Fe 3 + rich medium to increase magnetization signal generated by the electron spins originating from the ions. The magnetometry is performed by insulating the qubit device from the laden neurons with the polymeric film while keeping the distance between them around several micrometers. By changing temperature…

The SMPD can be used to detect spin echoes and that standard spin characterization measurements can be achieved with both echo and fluorescence detection, and the potential of SMPD detection as a method for magnetic resonance spectroscopy of small numbers of spins is discussed.

A novel approach to quantify different iron forms in ex-vivo human brain tissue

A novel combination of methods to study the physical properties of ferric ions and iron-oxide nanoparticles in post-mortem human brain, based on the combination of EPR and SQUID magnetometry, believe that this methodology could be beneficial in the study of neurodegenerative diseases such as Alzheimer’s Disease.
