Abstract
This study presents a comprehensive fabrication technology for LSPR sensors to address critical challenges, including high cost and low sensitivity. The fabrication process involves two key steps: the self-ordering growth of porous anodic alumina (PAA) and the template-assisted dewetting of thin gold film, resulting in a well-ordered AuNP layer. This work focuses on achieving large-scale ordering without lithography processes, improving the shape control of AuNPs, and exploring their utilization as gas sensors.
