Abstract Submission Template
-Instructions-  PLEASE READ
1.	Do not alter this template.
2.	Anything typed outside the “Replace this text with your abstract title/body” area will be ignored.
3.	For scientific equations, use only standard characters, Microsoft Equations Objects, or MathType.
4.	If you wish to embed a webpage, use the “Insert Hyperlink” function within Microsoft Word.
5.	Do not insert Charts or Images into the abstract.  This will cause your abstract to be rejected after submission.
6.	Do not retype author lists.  These will be automatically added; add only your abstract in between the “abstract” delimiters and your title in between the “title” delimiters.
7.	Do not alter the fonts or size/color of the text.  Such changes will be ignored and replaced with the standard.
8.	There is a limit of 1300 characters.  However, depending on such variables as the amount of “white space” or use of mathematical equations, some abstracts with less than 1300 characters will exceed our publication space limitations, and will be rejected. You will be able to preview your formatted abstract and check its length later in the submission process.
9.	When saving this document.  Use “File -> Save AS’ and save as an RTF document.  Please note the location where you save this document as you will need it when you upload it using the browse button.

    Magnetic Helical Microswimmers in Poiseuille Flow
-/title-

-abstract-
  We analyze the motion of artificial magnetic microswimmers which mimic the swimming of natural organisms at low Reynolds numbers. Artificial magnetic microswimmers consist of a rigidly connected helical tail and a magnetic head. Magnetic swimmers are actuated with three orthogonal electromagnetic coil pairs. The swimmer motion is examined in the laminar flow which is introduced to channel with syringe pump. We recorded videos for forward (pusher-like swimming / in the head direction) and backward (puller-like swimming / in the tail direction) motion of swimmers. Swimmers have non-stable helical trajectories for forward motion and stable straight trajectories for backward motion. The flow effects on trajectories are observed for swimmers with different geometric parameters in the circular channels. Experiment results show that helical wavelengths of the trajectories are affected with the flow. Additionally, the flow has more pronounced effect on the trajectories of the swimmers in wide channels. Moreover, circular confinement in narrow channels leads to more stable trajectories; in wide channels swimmers follow complex trajectories. A CFD model is used to compare experiments with simulations and to analyze the effects of hydrodynamic interactions.
