A tiny elephant establishes a new stomping ground for 3-D printing: inside cells.
For the first time, scientists have 3-D printed objects within living cells, including a 10-micrometer long elephant and tiny “barcodes” that could help track individual cells. Remarkably, many of the cells lived to tell the tale, researchers reported in a paper submitted June 16 at arXiv.org.
“It’s amazing to see that some of the cells actually do survive,” says biophysicist Kerstin Göpfrich of Heidelberg University in Germany, who wasn’t involved with the research. “Honestly, I wouldn’t have thought this. If you told me I would have been like, ‘Nah, never.’”
