Collective Response and Navigation Dynamics of Magnetospirillum gryphiswaldense under Rotating Magnetic Fields.

ABSTRACT: Magnetotactic bacteria (MTB) are aquatic microorganisms that biomineralize magnetic nanoparticles called magnetosomes, organizing them into chains that enable navigation along geomagnetic field lines. Their self-propulsion, magnetic responsiveness, and preference for low-oxygen environments make them promising candidates as biohybrid microrobots for biomedical and environmental applications. However, controlling large populations of MTB simultaneously remains a significant challenge. This study analyzes over 30 000 trajectories of Magnetospirillum gryphiswaldense (MSR-1) under rotating magnetic fields (RMF) of varying strengths (0 - 1000 µT) and frequencies (0.1-0.5Hz)$( {0.1 - 0.5 \; {\mathrm{Hz}}} )$ to characterize individual and collective motility behaviors. Trajectories shift from re
