Producing a substrate having high surface-area texturing
First Claim
1. A method comprising:
- providing a substrate having a material selected from the group consisting of polymeric materials, ceramic materials, glass materials, metal materials, composites thereof, and laminates thereof, wherein the substrate comprises a first surface having an initial surface area; and
performing a surface-altering process utilizing a partially transmissive mask that allows a fraction of light to pass therethrough, the surface-altering process altering the first surface of the substrate resulting in a surface area of the first surface that is greater than the initial surface area.

Abstract
A method is provided for preparing high surface-area texturing of a substrate using methods by which material from a substrate is subtracted from or added to the surface of the substrate. In one embodiment, the method is a subtractive lithographic method that involves exposing a laser-ablatable substrate, such as a polymeric or ceramic substrate, to laser light. A mask may be used to define the pattern of light incident on the substrate. High surface-area textured substrates, in particular, miniaturized planar analysis devices having high surface-area textured features, prepared by the methods disclosed herein, are also provided. A method by which the high surface-area textured substrate or the miniaturized planar analysis device is used as a master from which replicate copies thereof may be made is also provided.
