Abstract
A method for forming a chemically patterned surface includes subjecting a surface of a substrate to a fluid including a component such that the component reacts with the surface to form a first distribution of the component on the surface. Thereafter, the surface is deformed along at least one axis such that the first distribution of the component is converted to a second distribution different from the first distribution. The second distribution is a gradient of the component.
