Abstract

original image

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. Image created by Martin Rietveld.
