- Magnetic fields influence spin-correlated radical pairs (SCRPs), affecting living systems at the biomolecular level.
- Engineered SCRP systems can confer magnetic sensitivity to non-native biochemical processes in multicellular organisms.
- Control of SCRP dynamics using magnetic resonance was demonstrated in live transgenic nematode Caenorhabditis elegans.
- Red fluorescent proteins (RFPs) emission can be modified by static and radiofrequency magnetic fields near electron spin resonance frequency.
- Quantum-correlated radical pairs in RFP-flavin systems have coherence times larger than 4 ns.
- Radiofrequency magnetic fields can influence SCRP dynamics in vivo, enabling remote control of biomolecular processes like gene expression.
- Potential for quantum tools in biology is suggested by these findings.
