Abstract

The viability of a fiber optic reflection-based Localized Surface Plasmon Resonance (LSPR) sensor using layer-by-layer technique composed by PAMAM-AuNP with and without AuNP-citrate was investigated. The PAMAM-AuNPs and PAMAM-AuNPs/AuNP-citrate layers were deposited on the endface of an optical fiber and the reflected signal was acquired. Deposition time and number of layers were optimized viewing LSPR sensing applications. Results with and without AuNP-citrate were compared. The sensor is being characterized as a refractive index sensor.
