Nanoengineers can print 3-D microstructures in mere seconds

A novel technology can fabricate, in mere seconds, microscale three dimensional (3-D) structures out of soft, biocompatible hydrogels. The technology could lead to the ability to print biological tissues for regenerative medicine. Chen is able to print tissues that mimic nature's fine-grained details, including blood vessels, which are essential for distributing nutrients and oxygen throughout the body.
