1. A method of reversibly modifying a property of a surface, comprising:
- depositing a nanolayer of a material on a substrate; and
applying an external stimulus to the nanolayer, wherein;
when the stimulus is applied, the nanolayer shifts from a first conformation state to a second conformation state.

Abstract
A substrate having a surface with reversibly switchable properties. The surface comprises a nanolayer of a material that switches from a first conformation state to a second conformation state when an external stimulus is applied. When the nanolayer is in the first conformation state, the surface is characterized by a first property, and when the nanolayer is in the second conformation state, the surface is characterized by a second property.

58. A switch for a waveguide disposed at a junction between an incoming waveguide and first and second outgoing waveguides, the switch comprising:
a chamber having a surface and containing a liquid and a gas and an interface between them, wherein;
the surface comprises a nanolayer of a material characterized in that, when an external stimulus is applied, the nanolayer shifts from a first conformation state to a second conformation state, when the nanolayer has one of the first or second conformation state, light can pass through the liquid from the incoming waveguide to the first outgoing waveguide, and when the material has the other of the first or second conformation state, light from the incoming waveguide is reflected off the liquid-gas interface and directed into the second outgoing waveguide.

59. A substrate having a surface having at least first and second properties, wherein:
-
the first property is defined by a surface property of the substrate, the second property is defined by a surface property of a nanolayer deposited on the substrate, and the surface density of the nanolayer is adapted and constructed such that the interaction with the surface of a chemical entity having a size less than a predetermined size is defined by the first property and the interaction with the surface of a chemical entity having a size greater than the predetermined size is defined by the second property.

60. A method of reversibly modifying a property of a surface, comprising:
-
depositing a nanolayer of a material on at least a first portion of a substrate; and
applying an external stimulus to the nanolayer, wherein;
when the stimulus is applied, the nanolayer shifts from a first adsorption affinity to a second adsorption affinity, wherein the affinity is for an entity that adsorbs onto the surface. - View Dependent Claims (61, 62, 63)
