Abstract

Optically addressable spin systems have been widely studied for quantum-sensing applications. In this work, we demonstrate that photogenerated spin-correlated radical pairs in certain flavoproteins, cryptochrome and improved light–oxygen–voltage protein, can be manipulated by radio waves. This capability enables magnetic field sensing and spatial modulation of photoluminescence using radiofrequency pulses and magnetic field gradients, establishing proteins as a platform for optically addressable spin systems and radiofrequency-based control of biological processes.
