Magnetic Sensing of Magnetization in Magnetotactic Bacteria with Nitrogen Vacancy Centers in Dimond

Countless progress and efforts have been made toward cancer diagnosis and management upon frontier interdisciplinary. The outstanding physical and biochemical properties of the magnetsomes in magnetotactic bacteria find potential application in bioimaging and diagnostics of tumor. We present magnetic sensing of magnetization of the magnetsomes in magnetotactic bacteria using nitrogen vacancy centers in diamond. This work will provide a capability for biomagnetic structures like magnetotactic bacteria use in cancer diagnosis and cell engineering.
