Background<\/strong><\/p>\n

\"\"<\/p>\n

Magnetotactic bacteria (MTB) possess an exquisite orientation mechanism allowing them to move along the geomagnetic field lines. This mechanism consists of a chain of bio-synthesized magnetic nano-crystals that endow MTB with a permanent magnetic moment. Although the physics behind the minimum size of this biological compass is well understood, it is yet unclear what sets its maximum size. Here, by using a macroscopic experiment inspired in these microorganisms, we explore the impact of MTB having larger magnetic moments.<\/p>\n

In this research we will try to miniaturize the actual platform and explore the structures that form when we control magnetic moments and activity.<\/p>\n

 <\/p>\n

IRES student involvement.<\/strong><\/p>\n

Students will be trained in the basics of a model for magnetic active mater. Students will participate in the design and construction of smaller robots that mimic MTB, and we will measure their motion using high-definition cameras, and the short time scale motion will be characterized with high-speed imaging. Students will also learn how to calibrate magnets and the basic notions of correlations.<\/p>\n
