Imaging magnetic field signals from biological samples is a groundbreaking technique in fundamental biology, medicine, and clinical settings. One of the leading quantum platforms for magnetic imaging is the diamond's nitrogen-vacancy (NV) center [1]. The NV center carries an electronic spin of one that is addressable via laser and microwave irradiation and stable under ambient conditions. With these unique advantages, researchers have investigated magnetic field signals in numerous systems. In this talk, I will overview recent demonstrations of magnetic field imaging of wide-ranging biological systems, from living cells and neurons to mammalian hearts, with high sensitivity and spatial resolution [2-4].
