DNA Hybridization and Ligation for Directed Colloidal Assembly

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.
