Abstract: Magnetically driven biocompatible microrobots comprising a porous body having a magnetic layer and a biocompatible layer configured to carry and deliver cells to desired sites are described. Embodiments of microrobots are configured with enhanced cell-loading ability, such as by including a plurality of burr members disposed upon the porous body for configuring the microrobot for enhanced cell-loading. The magnetic layer of embodiments may be provided on some portion or all of a surface of the microrobot for configuring the microrobot to be controlled with an external magnetic field. The biocompatible layer of embodiments may be provided on some portion or all of a surface of the microrobot, possibly coating some or all of the aforementioned magnetic layer, for configuring the microrobot for improved biostability and biocompatibility.
