Encapsulation of the DNA-assembled plasmonic nanostructures in microfluidic droplets. (a) Self-assembly of the DNA-assembled plasmonic nanostructure. A DNA origami cross is assembled from the p7560 scaffold and staple strands. It is then functionalized with one AuNR on each arm of the cross to form a plasmonic nanostructure. (b) Schematic of the microfluidic encapsulation of DNA-assembled plasmonic nanostructures in water-in-oil droplets. Plasmonic droplets are formed at the microfluidic T-junction. (c) High-speed microscopy image (bright-field) of the encapsulation process. DNA-assembled plasmonic nanostructures are encapsulated via the aqueous channel of a microfluidic droplet formation device. Scale bar: 100 μm. (d) Bright-field and (e) confocal fluorescence image of the plasmonic droplets 24 h after encapsulation (stained with SYBR Green I, λex = 488 nm). Scale bar: 100 μm.
