Highly Ordered and Stable Silver Nanodot Pattern : From Fabrication to LSPR Applications |
| 초록 |
Silver has been explosively used for optical sensing and imaging applications which benefit from localized surface plasmon resonance (LSPR) in nanoscale configuration. Many attempts have been made to fabricate and control the silver nanostructure but, fatal mechanical weakness of silver have interrupted the manufacturing of reproducible and high-throughput nanostructures using the top-down lithography approach. In this study, we suggest a steady fabrication strategy to obtain highly ordered silver nanopatterns that is able to provide tunable LSPR characteristic and high performance in optical sensing system. By using protecting layer of platinum on silver surface for dry lithographic etching process, we successfully obtained large-area silver nanopatterns with high reproducibility. The large-area silver nanopatterned structures were capable of enhancing Cy3 flurophore labeled DNA signal with four order of magnitude of detection limit (~ 10-10M). |
