Abstract
Au nanoparticles grown on D- and L-isomers of diphenylalanine peptide nanotubes showed a bisignated CD signal at their surface plasmon frequency with positive and negative couplets, respectively. The surface plasmon coupled CD signal in these hybrid systems originates from the asymmetric organization of Au nanoparticles on peptide nanotubes. Mirror image relationship in the CD spectra clearly indicates that the chiral molecules on the nanotubes drive the organization of nanoparticles in two different ways.
