Thermally activated, untethered microgrippers can reach narrow conduits in the body and be used to excise tissue for diagnostic analyses. As depicted in the figure, the feasibility of an in vivo biopsy of the porcine bile duct using untethered microgrippers is demonstrated.
The first biopsy with untethered, sub‐millimeter scale grippers is described by David H. Gracias and co‐workers on page 514. The cover shows the retrieval of cells from the bile duct of a live pig using thermally responsive tether‐free m‐grippers. The retrieved tissue was of a high enough quality and quantity to enable both histological and molecular biology analyses which forms the basis of diagnostics...
