Bioinspired Helical Microswimmers Based on Vascular Plants
Nano Letters, 2013 Plant-based bioinspired magnetically propelled helical microswimmers are described. The helical microstructures are derived from spiral water-conducting vessels of different plants, harnessing the intrinsic biological structures of nature. Geometric variables of the spiral vessels, such as the helix diameter and pitch, can be controlled by mechanical ...

Surface-Chemistry-Mediated Control of Individual Magnetic Helical Microswimmers in a Swarm [PDF]
ACS Nano, 2018 Magnetic helical microswimmers, also known as artificial bacterial flagella (ABFs), perform 3D navigation in various liquids under low-strength rotating magnetic fields by converting rotational motion to translational motion. ABFs have been widely studied as carriers for targeted delivery and release of drugs and cells. For in vivo/in vitro therapeutic

Integral line-of-sight path following control of magnetic helical microswimmers subject to step-out frequencies [PDF]
Automatica, 2021 This paper investigates the problem of straight-line path following for magnetic helical microswimmers. The control objective is to make the helical microswimmer to converge to a straight line without violating the step-out frequency constraint. The proposed feedback control solution is based on an optimal decision strategy (ODS) that is cast as a ...

Planar Path Following of 3-D Steering Scaled-Up Helical Microswimmers [PDF]
IEEE Transactions on Robotics, 2015 Helical microswimmers that are capable of propulsion at low Reynolds numbers have great potential for numerous applications. Several kinds of artificial magnetic-actuated helical microswimmers have been designed by researchers. However, they are primarily open-loop controlled.

Physical Review E, 2015 Recently, there has been much progress in creating microswimmers or microrobots capable of controlled propulsion in fluidic environments. These microswimmers have numerous possible applications in biomedicine, microfabrication, and sensing. One type of effective microrobot consists of rigid magnetic helical microswimmers that are propelled when rotated
