METHOD OF PATTERNING A CURVED SURFACE WITH NANOSCALE FEATURES TO PREVENT BIOLOGICAL GROWTH

摘要

Disclosed is an article with a curved surface with a printed pattern to prevent the growth of living organisms. The article comprises a curved surface; the curved surface having disposed thereon a plurality of patterns; each pattern being defined by a plurality of spaced apart features attached to or projected into the curved surface, the plurality of features each having at least one neighbouring feature having a substantially different geometry, wherein an average spacing between adjacent spaced apart features is 1 nanometre to 1 millimetre in at least a portion of the curved surface, wherein the plurality of spaced apart features are represented by a periodic function, wherein each pattern is formed on the curved surface.
