Quantum spin resonance in engineered proteins for multimodal sensing.

ABSTRACT: Sensing technologies that exploit quantum phenomena for measurement are finding increasing applications across materials, physical and biological sciences^1-7. Until recently, biological candidates for quantum sensors were limited to in vitro systems, had poor sensitivity and were prone to light-induced degradation. These limitations impeded practical biotechnological applications, and high-throughput study that would facilitate their engineering and optimization. We recently developed a class of magneto-sensitive fluorescent proteins including MagLOV, which overcomes many of these challenges⁸. Here we show that through directed evolution, it is possible to engineer these proteins to alter the properties of their response to magnetic fields and radio frequencies. We fi
