Until now, the shape of active prolate ellipsoids has not been optimized to make these particles move in a straight line. This is particularly interesting because a straight moving particle can be used as a basis to model these biological systems. Simulations were done to optimize the shape of prolate ellipsoids for straightness of path and four variables are defined that quantify this. The paths of active prolate ellipsoids with a long semi axis of 5 μm and a short semi axis between 1 and 4.9 μm were simulated in C, and the straightness of path was compared using the variables. The simulations suggest that particles with a larger short semi axis follow straighter paths, although this needs to be supported by empirical results.Show less
