Nanoprinter could have cells lining up to be tested


By Colin Barras BORROWING a trick from the office photocopier may make it possible for a nanoscale printer to precisely manipulate biological cells for use in artificial tissue. In 2007, John Rogers at the University of Illinois at Urbana-Champaign and colleagues produced a printer small enough to print electronic circuits from conductive ink on the nanoscale. By modifying the technique, they think it should be possible to manipulate biological cells or biomolecules such as DNA,
