From: Self-healable stretchable printed electronic cryogels for in-vivo plant monitoring
Optical micrographs of transversal cuts of the tomato plant stem a without implants, and b with implants 1, 14, 30 and 120 days after implantation or cut (scale bar is 500 µm). In b, the implant is not always visible in the image as they were sometimes removed during the preparation process of the thin stem slices.
