Abstract:
1. A microparticle comprising: at least one oblong flexible tail configured to propel said microparticle in a solution along a trajectory using beats transverse to the trajectory, said tail comprising at least one magnetic element such that said magnetic element causes said beats of said tail under the action of an external alternating magnetic field non-collinear with the trajectory, a head mechanically connected to a proximal end of the tail, wherein said microparticle comprises at least one layer of material formed from one piece and comprising said tail and said head, the dimensions and/or shape of said head being selected such that the beats of said proximal end of said tail are limited with respect to the beats of the distal end of the tail such that said head does not make a complete revolution around an axis parallel to the trajectory under the effect of said external alternating magnetic field.
