Technological scheme for (bio)molecular patterning based on E-beam lithography and multistep self-assembly.Left:a A resist layer (PMMA) was deposited onto silicon dioxide by spin coating;b EBL patterning and development;c selective SAM deposition by self-assembly in the exposed regions of the substrate;d lift-off;e,f spatially confined self-assembling of cross-linking molecules and probe biomolecules.Right: real images of the stepsb,c andf, respectively.I Holographic microscopy 3D image of 1 μm wide PMMA stripes after EBL patterning and development;II confocal microscopy image of FITC-labeled APTES stripes (features: 20 μm); andIII confocal microscopy image of Cy3-labeled ssDNA stripes (features: 20 μm)
