Abstract
The unique optical properties of gold nanorods (AuNRs), arising from their anisotropic structure, have made them a subject of great interest across diverse applications. AuNRs exhibits two distinct localized surface plasmon resonance (LSPR), that, the color variation of AuNRs is primarily attributed to the dependence of their longitudinal LSPR peak on their aspect ratio; even minor shifts in the longitudinal position can lead to significant color changes. This high sensitivity and broad spectral tunability render AuNRs ideal candidates for the design of highly accurate and visually discernible colorimetric sensors. This study explores the design and development of colorimetric sensors based...
