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.

Protein Dynamics in Living Cells
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
