Abstract:
1. A method of patterning a material surface comprising: providing a stamp having a structure including at least one non-linear fluid flow path therein in fluid communication with a stamping surface of the structure, the non-linear fluid flow path comprising a first channel segment thereof disposed within an interior region of the stamp structure and not completely traversing an entire thickness of the stamp structure, and a second channel segment thereof formed by an indentation disposed within the stamping surface of the structure, and said first and second segments being fluidically interconnected so fluid can flow from the first segment to the second segment; contacting the stamping surface with a portion of the material surface; and while maintaining the stamping surface in contact with the portion of the material surface, at least partially filling the flow path with a fluid so that at least a portion of the fluid contacts the material surface from the indentation to provide a pattern on the material surface.
