Visual surface plasmon resonance biodetection apparatus

Abstract

A visualized surface plasma resonance biosensor device defines an optical path and includes a first optical module, a surface plasma resonance biosensor, and a second optical module. The first optical module is disposed on the optical path and provides an infrared beam traveling to the surface plasma resonance biosensor. The surface plasma resonance biosensor is disposed on the optical path and emits a reflected beam when illuminated by the infrared beam. The surface plasma resonance biosensor includes an optical prism and a sensing element. The sensing element includes an active layer and a metal layer spaced apart from the optical prism. The metal layer connects to the active layer and is disposed between the active layer and the optical prism. The second optical module is disposed on the path and converts the reflected beam into visible light, and includes an up-converter.
