Micro- and nanoscale patterning of functional proteins. (Left) confocal microscopy images of stripes of GFPs, with features ranging from 5 μm to 500 nm (afluorescence line profile is also reported in the inset of the 2 μm wide GFP stripes). (Right,top) Emission spectrum of patterned GFPs as compared to the native proteins in solution. (Right,bottom) AFM image and line profile of a GFP pattern with 1 μm features
