Selective nanodecoration of modified cyclodextrin crystals with gold nanorods
Tóm tắt
Gold nanorods (AuNRs) stabilized by cetyltrimethylammonium bromide (CTAB) were deposited onto crystals of α-cyclodextrin (α-CD) inclusion compounds (ICs) that contained octanethiol (OT) as guest molecules. The nanodecoration was produced specifically at the {001} crystal planes through interaction between the –SH groups of the ICs and the AuNRs.
