Self-Assembly of gold nano particles on templated patterns formed by wrinkling |
| 초록 |
Surface-ordered nanoparticles were studied via template-guided self-assembly of spherical monodisperse gold nanoparticles in wrinkled templates. Surface instability and pattern formation based on difference in thermal expansion between bilayers was employed as a guidline for patterned particle assembly. Tuning the wrinkle’s wavelength enables us to precisely confirm the assembly morphology and fabricate line and complex nano-particles patterns. Furthermore, surface charge on wrinkles can be changed using different silica precursors. It helps to arrange gold nanoparticles in wrinkles or cover nano-colloids on wrinkled surface controlling electrostatic interaction between particles and surface. It is expected that highly regular 1- and 2-dimensional patterned nano gold colloids will be promising candidates for various applications such as sensors, surface enhanced raman spectroscopy, photovoltaics or plasmon enhanced solar cells. |
