Fluorescent proteins which seem magnetically inert (e.g. EGFP, mScarlet) become magnetoresponsive in the presence of an appropriate cofactor (e.g. EGFP-FlavinTag, or an mScarlet/FMN solution). This method works at room-temperature and body-temperature, in vitro, in E. coli and in cultured mammalian cells. The GFP-family magnetoresponse is weak ( Δ F / F ≈ 1 % Δ 𝐹 / 𝐹 ≈ 1 % ), but shows the hallmarks of evolvability. This suggests exciting technological possibili
