In this study, manganese‐based multiply hierarchical chiral supraparticles (SPs), with an anisotropy factor (g‐factor) of 0.102 and circular dichroism (CD) intensity of 260 mdeg at 530 nm, are successfully synthesized with polar‐solvent‐mediated strategies. Notably, the g‐factor of the SPs is further enhanced to 0.121 by the addition of an external chiral solvent, generating a chiral biased environment,...
H. Kuang and team develop Au core‐DNA‐Ag shell nanoparticles (NPs) with distinctive chiroplasmonic performances for the first time on page 850. The NPs exhibit very intense CD activities with the highest g‐factor value. The CD responses of the individual NPs can be controllably manipulated by altering the Ag shell thickness. The optically active NPs open up avenues for chiral catalysis and chirophotonic...
The strong plasmonic chiroptical activities of gold core‐DNA‐silver shell nanoparticles (NPs) are reported for the first time, using cytosine‐rich single‐stranded DNA as the template for the guidance of silver shell growth. The anisotropy factor of the optically active NPs at 420 nm reaches 1.93 × 10−2. Their chiroptical properties are likely induced by the DNA–plasmon interaction and markedly amplified...
