Fabrication of Dual Functionalized Surfaces on a Patterned SiO2/Au Template via Si-containing Block Copolymer |
| 초록 |
Chemical surface nanostructures were obtained using self-assembled monolayers patterned by microcontact printing or nanoimprint techniques. But these approaches are inadequate at the micron- and sub-micron scales. Serial techniques like electron-beam lithographies achieve nanoscale pattern definition but are limited in their ability to define large area patterns. In this study, we use Si-containing block copolymer lithography for fabricating highly ordered nanoporous SiO2 structures on gold substrates. The materials with silanol end groups self-assembled on the SiO2 surface, while the compounds with the thiol groups on the gold surface. This patterning method not only form ordered nanostructures over large area, but also control surface property by changing functional groups of self-assembled molecules. These dually patterned surfaces would be further utilized for immobilization materials and highly useful for the high throughput biosensor and array applications. |
