摘要:
A plasmonic nanostructure includes two plasmonic nanorods spaced apart by a gap and interconnected by a conductive junction spanning the gap, and mimics a longer nanostructure. This provides an ability to tune a structure in wavelengths that would be difficult to otherwise achieve.
摘要:
A genetically modified cowpea mosaic virus (CPMV) protein capsid serves as a scaffold for metal nanoparticles, preferably gold nanospheres, of 15 nm to 35 nm, creating plasmonic nanoclusters. The self-assembled nanoclusters gave rise to a 10-fold surface-averaged enhancement of the local electromagnetic field. Other viral capsids or virus-like proteins may also serve as such scaffolds.
摘要:
A method of forming a monolayer film of nanoparticles includes forming a fluid mixture by combining nanoparticles dispersed in water with a water-miscible organic solvent and a molecular ligand comprising a head group with affinity for the nanoparticle, and introducing the fluid mixture to a substrate in the presence of an air/fluid interface, thereby causing a monolayer film of nanoparticles to form on the substrate. Such monolayers films can include metallic nanoparticles such as gold, and possess substantially uniform spacing over at least a one centimeter length scale.
