Claim:
1. A method comprising: applying an external stimulus to a surface of a substrate; adjusting at least a portion of the surface from a first state to a second state, wherein either (i) the first state presents a substantially hydrophobic surface and the second state presents a substantially hydrophilic surface; or (ii) the first state presents a substantially hydrophilic surface and second state presents a substantially hydrophobic surface; contacting the surface in the second state with a fluid or gas, the fluid or gas having one or more decontaminating agents effective on one or more contaminates associated with the surface of the substrate; removing the external stimulus to the surface of the substrate, the surface transforming from the second state back to the first state, whereby at least a portion of the surface of the substrate is decontaminated.
