Forscher haben die Blaupausen und Anleitungen zum 3D-Druck einer Hasen-Figur in DNA-Strängen gespeichert, diese in verschiedene Materialien eingebettet und mit diesen wiederum genau diesen Hasen auf einem 3D-Drucker ausgegeben. Rekursive DNA-Bunnies sind die besten DNA-Bunnies.
Produced from a partnership between Israeli and Swiss labs, the figurines encase synthetic DNA that holds the code required to 3D print more bunnies. In further tests, they were able to extract the computer code and “reproduce” the bunnies, the researchers write. It’s a proof-of-concept that showcases DNA’s potential as a hyper-dense medium for future data storage. […] In this case, the researchers took it a step farther by putting the data-carrying DNA into the object it encodes — much like our own cells hold the DNA instructions for our entire bodies.
First, the team spelled out the instructions for the bunny with lab-made DNA. To keep the molecules from getting damaged in the 3D printer, they encased the DNA strands in silica, the chemical that makes up quartz. Only then did the researchers put the little silica packages in a plastic that could be pumped through a 3D printer. The end result was a plastic rabbit suffused with molecules of artificial DNA.
