Developments in bioengineering keep moving the needle between reality and science fiction. From genetic editing with the CRISPR-Cas system and growing functioning organoids in petri dishes to brain cells on microchips — scientists continue to surprise us with cutting-edge inventions.
Now, for the first time, researchers from the Department of Condensed Matter Physics at the Jožef Stefan Institute in Ljubljana, Slovenia, established a method to 3D print microscopic structures inside living human cells. To demonstrate the detail and versatility of the technology, they printed a tiny elephant, alongside other microscopic geometric objects and barcodes for cell labeling, into the interior of a cell.
