In recent years, there has been growing interest among researchers in plasmonic nanosensors for the detection of different analytes. In this work Localized Surface Plasmon Resonance (LSPR) nanosensors based on gold Thue-Morse nanopatterns with different shapes and sizes were fabricated by the use of the Electron Beam Litography process. The sensitivity,the Figure of merit of the nanosensor and the limit in detection of a pesticide (Thiram, C6H12N2S4 ) were evaluated and reported. We systematically investigated the size- and shape-dependent LSPR activities of plasmonic Thue-Morse nanorods towards detection of the pesticide thiram. Gold Thue-Morse nanopatterns with different shapes and sizes were fabricated by EBL. Sensitivity, figure of merit and limit in detection of the pesticide were evaluated and reported.

Abstract
In recent years, there has been growing interest among researchers in plasmonic nanosensors for the detection of different analytes. In this work Localized Surface Plasmon Resonance (LSPR) nanosensors based on gold Thue-Morse nanopatterns with different shapes and sizes were fabricated by the use of the Electron Beam Litography process. The sensitivity,the Figure of merit of the nanosensor and the limit in detection of a pesticide (Thiram, C6H12N2S4 ) were evaluated and reported. We systematically investigated the size- and shape-dependent LSPR activities of plasmonic Thue-Morse nanorods towards detection of the pesticide thiram. Gold Thue-Morse nanopatterns with different shapes and sizes were fabricated by EBL. Sensitivity, figure of merit and limit in detection of the pesticide were evaluated and reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
