A quick protocol for the fabrication of ultrahigh density arrays of toroidal ZnO nanostructures with tailored structures on a substrate surface is presented based on the one-step spin coating of a common solution composed of inverse micelles of polystyrene-block-poly(4-vinyl pyridine) copolymers (PS-b-P4VP) and sol-gel precursors without the need of conventional complex lithographic techniques. ZnO toroids decorated with gold nanoparticles are also obtained by subsequent loading and reduction of metallic precursors. It was elucidated that the diethanolamine moiety in the sol-gel precursors, which induces selective swelling and structural reorganization of the P4VP core blocks, plays a key role in the generation of toroidal nanostructures. Toroidal ZnO nanostructures embedded in a PS-b-P4VP matrix films or arrays of pure wurtzite ZnO nanorings are obtained by calcination under inert atmosphere. The structural parameters of the toroidal nanostructures such as the width, height, diameter of the rims as well as the spacing of their 2D arrays are controlled by employing PS-b-P4VP with different molecular weight and varying the mixing protocols.

“…3. The absorption values of Au nanoparticles and ZnO-Au nanocomposites in water are centered at 520 and 546 nm, respectively [26]. The red shift of the surface plasmon spectrum of the ZnO-Au nanocomposites is due to the strong interfacial coupling between Au and ZnO.…”

“…The other is that Au nanoparticles couple with antigen and Au-antigen binds to the antibody immobilized on the SPR biosensor [25]. ZnO-Au nanocomposites were used to modify a SPR biosensor chip by a self-assembly technique in our previous work [26]. Here, instead of immobilization of ZnO-Au nanocomposites on the SPR biosensor chip directly, ZnO-Au nanocomposites were used to couple with antigen to construct the protein probe.…”
