Herein we demonstrate the construction of three types of parallel gold nanorod (AuNR) clusters using a DNA origami rod (DOR) as the template. Based on the precise control over the position of capture strands on DOR, number and orientation of the AuNR clusters can be well engineered, as evidenced by biological transmission electron microscope (TEM). Importantly, the AuNR clusters exhibit chiroptical responses which are strongly affected by the number of AuNR on rod-like DNA origami.
