Our findings reveal that a surface active microrobot is by far more efficient in moving through blood than a non-surface active microrobot. This is because the surface velocity of the microrobot pushes the blood cells laterally, allowing them to propel themselves into the hole they are digging. When the microrobot size is comparable to a red blood cell, the puller microrobot swims faster than the pusher microrobot. However, when the microrobot size becomes much smaller, the pusher microrobot swims faster than the puller microrobot. These results offer valuable insights into the design of microrobots efficiently navigating through blood for targeted drug delivery and minimally invasive medical procedures.
