Paper Abstract

Two mechanisms can be applied initially for the high resolution patterning on radiation-assisted functionalized polymer surfaces: hydrophobicity-controlled patterning; and chemical linkage. The present contribution assesses the merits and drawbacks of these mechanisms in terms of resolution and contrast of protein/peptide features. Two microlithographic materials (an acrylate-based system and a diazo-naphto-quinone one); and two lithographic methods (e-beam and optical) have been used to test the merits of the protein patterning mechanisms. The hydrophobicity-controlled patterning produces sharp images but with multiple defects, whereas chemical linkage produces defect-free images but with a decreased contrast. The benefits of a third mechanism for protein confinement, namely bimolecular specific recognition, was explored in the view of the possible fabrication of artificial molecular motors.
