摘要
Au core-DNA-Ag shell nanoparticles (NPs) are successfully fabricated for the first time. They exhibit very intense circular dichroism activities in the visible range, with the highest g-factor value for the individual NPs with chiroplasmonic activity. The plasmonic mechanism is explored, which is from the induction of DNA-plasmon interaction and further amplification by the electromagnetic coupling of the core–shell structure.
