Controllable fabrication of polymeric nanowires by NIL technique and self-assembled AAO template for SERS application

Abstract A controllable strategy to fabricate the polymeric nanowires with high throughput and low cost is developed by using the thermal nanoimprint lithography (NIL) technique and self-assembled anodic aluminum oxide (AAO) template. The length of polymeric nanowires can be controlled by adjusting...
