Abstract
|
For decades, plasmonic nanostructures have been used as important optical sensing platforms, however, the necessity of sensitive optical instruments for detection greatly limits their practical application. Herein, a multi-responsive naked eye plasmonic indicator has been prepared through introduction of a responsive polymer brush (PNIPAm) into the cavity of a Ag nanovolcano array (Ag NVA). According to the phase change of the PNIPAm brush under different external conditions, the as-prepared Ag NVA shows responsive monochromatic colors, which allow the Ag NVA to serve as a plasmonic indicator detected by the naked eye. Importantly, the as-prepared Ag NVA also possesses a rapid response rate as well as excellent repeatability, and is compatible with conventional micro-fabrication methods. All of these excellent features make the as-prepared Ag NVA an attractive candidate for future optical indicating and intelligent color display applications.
