제목 DNA functionalization of colloidal particles via physisorption of azide functionalized diblock copolymers
초록 DNA-coated inorganic particles can be prepared simply by physical adsorption of azide-functionalized diblock copolymers (polystyrene-bpoly( ethylene oxide)-azide, PS-b-PEO-N3) onto hydrophobicallymodified inorganic particles, followed by strain-promoted azide–alkyne cycloaddition (SPAAC, copper-free click chemistry). This approach is applied to organosilica, silica and titania particles. The DNA-coated colloids are successfully crystallized into colloidal superstructures by a thermal annealing process using DNA-mediated assembly.
