Abstract: A visualized surface plasmon resonance biological detection apparatus defines an optical path and includes a first optical module, a surface plasmon resonance biosensor, and a second optical module. The first optical module is disposed on the optical path and is used to provide an infrared light beam. The surface plasmon resonance biosensor is disposed on the optical path, is used to reflect the infrared light beam to generate a reflected light beam, and includes an optical prism and a sensing member that includes a metal layer and an active layer which is spaced apart from the optical prism. The metal layer is connected to the active layer and is disposed between the active layer and the optical prism. The second optical module is disposed on the optical path to convert the reflected light beam into visible light and includes an up-converter.

Abstract: A detecting device is used for detecting existence of target biomolecules in a specimen with use of antibody complexes labeled with fluorescent molecules. The detecting device includes a capture member coated with capture antibodies for immobilizing the antibody complexes on the capture member when the target biomolecules exist in the specimen, a light emitting unit emitting a beam for exciting the fluorescence molecules to generate a fluorescence signal, and a signal processing unit for receiving the fluorescence signal and determining existence of the target biomolecules in the specimen based upon receipt of the fluorescence signal.
