Abstract
Spatiotemporal control of motility is an important function for bacteria as they seek energy sources. Magnetotactic bacteria utilize a chain of ferromagnetic particles to form an effective compass needle that allows them to seek the oxic-anoxic border in their environment, where optimal food sources are present. The specific mechanism of synthesis and mechanical behavior of particles in vivo is not completely understood. To understand the self-assembly and mechanical behavior of these magnetic nanoparticles, we produced micro-patterned strings of synthetic nanoparticles, using isolated magnetosomes, the ferromagnetic organelle composed of magnetite, from Magnetospirillum magnetotacticum.
