摘要	The structural and optical properties of DNA-mediated Au-Ag Janus nanostructures (JNs) are comprehensively studied by X-ray and optical techniques. The theoretical model for small angle X-ray scattering of Au-Ag JNs is proposed, and the fitting process is outlined. A hybrid junction consists of DNA and Ag is introduced in order to reconcile the discrepancy between the experimental and simulated optical spectra of Au-Ag JNs. The physical origins and controlling factors of the localized surface plasmon resonance modes are determined, which lay the foundations for managing and exploiting the unique plasmonic properties of Au-Ag JNs.
