Significance We demonstrate noninvasive detection of action potentials with single-neuron sensitivity, including in whole organisms. Our sensor is composed of quantum defects within a diamond chip, which detect time-varying magnetic fields generated by action potentials. The sensor is biocompatible and can be brought into close proximity to the organism without adverse effect, allowing for long-term observation and superior resolution of neuron magnetic fields.
