Soft lithography based micron-scale electrophoretic patterning of purple membrane
Abstract
Soft lithography and thermal evaporation of gold were used to create microfluidic channels with metal only on the bottom surface of each channel, in a process similar to nanotransfer printing (nTP). Micron-scale patterns of the bioelectronic material purple membrane (PM) were fabricated by combining standard soft lithography with electrophoretic deposition. Each metallized microfluidic channel is converted into a micron-scale electrophoresis cell by filling with a PM solution and applying a small voltage. Any number of patterns can be created for a variety of bioelectronic device applications. While this study focuses exclusively on the patterning of PM, micro-electrophoretic sedimentation is applicable to a wide range of biological and organic macromolecules.
