Some researchers are attempting to use the open-source Fab@Home printer to construct living tissues.FLICKR, ROBERT HUNTAs 3-D-printed tissues and organs slowly make their way toward the clinic, researchers are finding creative side-uses for the computerized manufacturing technology, The New York Times reported.
For instance, researchers at the University of Illinois are building “biobots,” miniature springboards made of cardiac muscle cells that inch forward as the cells beat. Such devices could travel around within a patient’s body to deliver drugs or find and destroy toxins.
“Our goal coming into this was the holy grail—organ printing,” Vincent Chan, who worked on the project as a postdoc at the University of Illinois at Urbana-Champaign and is now at the Massachusetts Institute of Technology, told NYT. “But, obviously, it’s very complex and very difficult.”
Others are shooting for making lab studies more effective by creating small patches of tissue for in vitro experimental use. The San Diego company Organovo, for instance, is developing printed “strips” of liver cells for drug testing.
