MRI driven magnetic microswimmers.
Capsule endoscopy is a promising technique for diagnosing diseases in the digestive system. Here we design and characterize a miniature swimming mechanism that uses the magnetic fields of the MRI for both propulsion and wireless powering of the capsule. Our method uses both the static and the radio frequency (RF) magnetic fields inherently available in MRI to generate a propulsive force. Our st...
متن کاملPropulsion and Chemotaxis in Bacteria‐Driven Microswimmers
Despite the large body of experimental work recently on biohybrid microsystems, few studies have focused on theoretical modeling of such systems, which is essential to understand their underlying functioning mechanisms and hence design them optimally for a given application task. Therefore, this study focuses on developing a mathematical model to describe the 3D motion and chemotaxis of a type ...
متن کاملMagnetically driven colloidal microstirrer.
Paramagnetic colloidal particles dispersed in water and deposited above magnetic bubble domains of a uniaxial ferrimagnetic garnet film are used as microscopic stirrer when subjected to external rotating magnetic fields. The hydrodynamic flow field above the stirrer is detected by tracking of nonmagnetic microspheres. The vorticity of the flow falls off inversely proportionally to the distance ...
متن کاملMagnetically driven single DNA nanomotor.
In biological systems, nanoscale molecular motors can generate forces from spontaneous reactions of energy-rich molecules, mostly adenosine triphosphate (ATP), to convert chemical energy into mechanical movement. These motors are roughly 10 nm in size, take steps of a few nanometers, and can exert forces in the piconewton range. [ 1 , 2 ] However, to effi ciently design and construct nanoscale ...
متن کاملChemotaxis of bio-hybrid multiple bacteria-driven microswimmers
In this study, in a bio-hybrid microswimmer system driven by multiple Serratia marcescens bacteria, we quantify the chemotactic drift of a large number of microswimmers towards L-serine and elucidate the associated collective chemotaxis behavior by statistical analysis of over a thousand swimming trajectories of the microswimmers. The results show that the microswimmers have a strong heading pr...
