Abstract

The invention relates to an article having a photoresponsive surface, said article comprising a substrate having photoionisable moieties capable of undergoing dimerization attached to at least a portion of a surface thereof, the proximity of said moieties to one another being such that irradiation with light of an appropriate wavelength results in dimerization of at least a portion of said moieties thereby altering the wettability of the surface. Methods of preparing a substrate having a photoresistive surface and methods for altering the wettability of a surface of a substrate are also included.
