Abstract
Nanopatterned devices are easily fabricated, over large surface areas when desired, by forming a multilayer article of deformable substrate, brittle layer, and coating layer, and deforming the multilayer film such that a plurality of cracks are formed therein. The cracks have different physicochemical properties than the non-cracked coating layer, and advantageously serve as attachment points for culturing microorganisms.
Claims24
A method for nanopatterning of a substrate, comprising:
- a) supplying a multilayer article comprising at least one deformable substrate, at least one brittle layer, and at least one coating layer adjacent said brittle layer, said coating layer having different physicochemical properties than said brittle layer;
- b) exerting a strain on said multilayer article such that cracks develop in said brittle layer exposing surfaces in said cracks having no coating layer thereon.
A nanopatterned device comprising:
- a) a deformable substrate;
- b) a brittle layer on at least one side of said deformable substrate, and having a first set of physicochemical properties;
- c) a coating layer on a side of said brittle layer remote from said deformable substrate, said coating layer having a second set of physicochemical properties different from said first set of physicochemical properties;
- and
- d) cracks through said coating layer and into said brittle layer, surfaces of said cracks exhibiting physicochemical properties different from said second set of physicochemical properties.
