The creation of replicated human body parts and organs may seem far-fetched, but a team of scientists in Austria has demonstrated just how easy it can be.
Using advanced 3-D printing methods, the researchers are creating nano-sized sculptures to show the technology’s potential in bio-medical science. The method uses lasers and photon-sensitive liquid resin to create structures on the scale of sand grains in a relatively short period of time.
Jan Torgersen, main developer of the 3-D printing technique, says that this technology will soon be applied in biomedicine:
“We are eagerly trying to develop low-toxic resins, which can be cured under the two-photon condition. These structures can actually resemble biological tissue or biological surroundings and we have a couple of publications currently under review, which are dealing with this. So we created these three-dimensional, very accurate structures and are hoping to get biologists to work with us on this very fascinating technique.”
