Colloidal-crystal-assisted imprinting (CCAIP), an alternative mesoscopic imprint approach, has been used to fabricate two-dimensional mesoscale polymer patterns, hierarchical multilayered or hybrid patterns. The Figure shows the hierarchical pattern that was fabricated by the combination of patterned poly(dimethylsiloxane) stamps and colloidal crystals.
