Figure 3. Guided navigation of a single cell gripper through fixed human fallopian tube tissue.

Figure 3.

(a) An open gripper moving in a slice of ex vivo human fallopian tube tissue, guided by a gradient magnetic field. (b) (i-iv) Optical snapshots show the gripper actuation upon temperature increase at the bifurcation site within the biological conduits. (c) (i-iii) Optical snapshots show the closed gripper being navigated leaving the biological conduit. The hematoxylin and eosin (H&E) stained tissue slice was dissembled from a commercially available microscope slide.
