Abstract:Another conventional method of colloidal assembly we pursued was sedimentation via slow centrifugation. The salt requirement for DNA hybridization and ligation made it necessary to use slow salt addition through a dialysis membrane to achieve well-ordered colloidal crystals. Well-ordered hexagonally close-packed polystyrene colloid monolayers could be assembled by sedimentation, hybridization, and ligation. Layer-by-layer assembly is also possible on the sedimented colloidal crystals. Since the drying and liquid-air interface effects experienced during vertical deposition are not a factor for sedimented colloidal crystals, we attempted to use templated substrates, created by imprint and holographic lithography, to assemble non-FCC colloidal crystals.
