Northwestern University Researchers Write Protein Nanoarrays Using A Fountain Pen And Electric Fields  
10/14/2008 8:18:50 AM -- Nanotechnology offers unique opportunities to advance the life sciences by facilitating the delivery, manipulation and observation of biological materials with unprecedented resolution. The ability to pattern nanoscale arrays of biological material assists studies of genomics, proteomics and cell adhesion, and may be applied to achieve increased sensitivity in drug screening and disease detection, even when sample volumes are severely limited.
