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.
