Patent number: 7636502Abstract: An optical waveguide bio-sensing device, comprising: a monochromatic light source, a beam splitter, a grating chip with a sub-wavelength grating structure and a sensor. Moreover, in order to enhance the sensitivity of the system using the optical waveguide bio-sensing device, a light concentrating element or a quarter waveplate (¼?) is arranged in the optical path during detection. When the grating chip is not coated with a layer of biochemical substance corresponding to a monochrome light emitted from the monochromatic light source, a reflected light of a specific narrow wavelength is reflected by a specific angle as a surface plasmon resonant effect caused by waveguide coupling is excited by the incidence of the monochrome light to the grating chip through the beam splitter; otherwise, there will be little or no reflection. Accordingly, the optical waveguide bio-sensing device can detect bio-molecular interactions, reaction rate and/or molecular dynamics without any labeling in real time.Type: GrantFiled: October 2, 2006Date of Patent: December 22, 2009Assignee: Industrial Technology Research InstituteInventors: Yen-Chieh Mao, Jian-Shian Lin, Lai-Sheng Chen, Wei-Han Wang
