  • Patent number: 10627406
    Abstract: A method for detecting glutathione includes mixing a sample including glutathione, 9-bromomethyl acridine (Br-MA) and a derivatization solvent to form a reaction solution. A derivative reaction occurs between Br-MA and glutathione to obtain a derivatization solution including a glutathione derivative with a thiol group being substituted with a tag. Excess Br-MA is removed by adding an interference removing solvent into the derivatization solution, followed by vortexing and centrifugation to obtain an aqueous layer solution. The aqueous layer solution is used as an analytic solution, and the glutathione derivative in the analytic solution is detected to obtain a glutathione value. The present invention also provides a kit for detecting glutathione which is adapted to carry out the method for detecting glutathione.

  • Patent number: 10598857
    Abstract: A pin hole or aperture is located or formed adjacent to the end surface of one or more of the input ports or fibers, or adjacent to one or more of the output ports or fibers, of a fiberoptic component. The aperture allows light to enter (or exit) the core of the associated fiber, and the non-transparent layer that surrounds the aperture blocks light from entering or exiting the cladding layer of the associated fiber. This blocking of the evanescent field in the cladding layer serves to reduce the polarization, wavelength, and temperature dependencies of the light coupling to the output port(s) or fiber(s) of the optical component. It can also reduce the passband width of the selected wavelength in tunable optical filter applications. The non-transparent layer surrounding the aperture can be made reflective, and light that is reflected by the non-transparent layer can be used for optical power monitoring.
