This is probably the case. Through the application of external magnetic fields, microrobots can be remotely controlled within the microfluidic channel to facilitate rapid and accurate transportation to the target point.
In the study, the team developed a microrobot by internalizing highly biocompatible and superparamagnetic iron oxide nanoparticles into stem cells extracted from human turbinate bones.
It can perform rolling motion through an externally controlled rotating magnetic field and translate through magnetic field gradients, enabling efficient transportation in various physiological environments within the body.
