Apparatus of Localized Surface Plasmon Sensor Using Ordered Nano-Sized Metal Structures and Method Manufacturing the Same

摘要

The invention prism; The substrate with the top of the prism; The metal thin film provided on top of the substrate; The T-shaped metal structure having more than one on top of the metallic thin film; A light source that is provided to ensure that the predetermined distance apart on one side of the lower substrate passes through the substrate to emit incident light that is incident to the metal thin film; Relates to localized surface plasmon sensor including a light-receiving unit which is provided such that the predetermined distance spaced apart from the bottom of one side of the substrate detected by the changed optical localized surface plasmon resonance absorption to incident light. ; The present invention has the effect that by providing the metal thin film and a T-shaped metal structure on top of the substrate, leading to local surface plasmon resonance phenomenon, and, thereby improve the measurement sensitivity of the sensor. ; Surface plasmon resonance, localized surface plasmon, a prism, a light source, a sensor
