Has been so cool to follow this fantastic work, congrats! Conclusion mentions “improving the release efficiency by enhancing the specific heat absorption rate of the nanoparticles” could this enable multiplexed control - different frequencies activating different nanoparticles in the same cell?

MagLOV quantum sensing update! Much improved imaging (>10% single cell ODMR contrast), detailed characterisation and simulation, and new experimental demonstrations taking us a step closer to applications.

$A. Structure of AsLOV2 PDB~2V1A (Halavaty, 2007) with mutations resulting in MagLOV~2 highlighted. Spin transitions driven by radio-frequency (RF) fields in the presence of a static magnetic field are optically detected via fluorescence measurements on an otherwise standard widefield microscope. Similar effects have recently been observed in other protein systems (Burd 2025, Meng 2025, Feder 2025). B. Simplified photocycle diagram in the case of a large external magnetic field. C. A single cell expressing MagLOV 2 displaying an MFE of ~50% (measured as a change in fluorescence intensity in the presence of an applied field). For MFE measurements, the magnetic field was switched between 0 mT and 10 mT. D. Black dots: data from a single cell expressing MagLOV 2 displaying an ODMR signal with ~10% contrast. The static field B_0 is ~21.6 mT. Blue line (shade): the mean (std) of all single cell data in a field of view (~1000 cells). E. The static magnetic field B_0 was varied by adjusting the magnet's position, and ODMR spectra recorded. Red-lines are Lorentzian fits. Blue line is a theoretical prediction (i.e. is not a fit) of the expected resonance frequency of an electron spin with $\bar\gamma_e$=28 MHz/mT.$ Electronics, radio electronics, optical parts, and an animal sized MRI coil are assembled to perform fluorescence MRI measurements using MagLOV.
