Paper Abstract

This study attempts to assess the feasibility of building purposefully designed molecular motor arrays, the proteins responsible for the movements of the living organisms and cells. The 'building' process used high-resolution e-beam patterning, originating in semiconductor technology, upgraded to make biomicrolithography compatible with the patterning of bioactive molecules. The material used as a scaffold for the array [a copolymer of poly(tert-butyl-methacrylate/methyl- methacrylate)] was tailored to exhibit large difference in hydrophobicity when exposed to e-beam exposure. The e-beam patterning exposure-induced difference in hydrophobicity is responsible for the selective attachment of the myosin molecules on the patterned deep-submicron 'tracks,' and the higher concentration of 'guiding' molecules selectively confines the movement of the actin filaments.
