  • Publication number: 20210325399
    Abstract: A fluorescent probe having a capsule of nanometric size and an aggregate of fluorogenic molecules coupled to the capsule is provided. The aggregate emits a fluorescent signal at one or more wavelengths within the fluorescence spectral range when the probe is illuminated by an excitation light beam at one or more wavelengths within the excitation spectral range. Preferably, the fluorescent spectral range is in the near-infrared region of the spectrum. In some embodiments, the capsule is a boron nitride (BN) nanotube and the aggregate comprise 3,6-Bis[2,2]bithiophenyl-5-yl-2,5-di-n-octylpyrrolo[3,4-c]pyrrole-1,4-dione as fluorogenic molecules. In some embodiments, the 3,6-Bis[2,2]bithiophenyl-5-yl-2,5-di-n-octylpyrrolo[3,4-c]pyrrole-1,4-dione fluorogenic molecules are in a J-aggregation state.

  • Patent number: 9791439
    Abstract: A component or device is provided for the detection or the measurement in parallel of one or more specific types of biological or chemical target products. This component includes a group of nanotubes selected and/or functionalized to interact with the target product, around an optical waveguide. Thus, an optical coupling is produced between the optical waveguide and one or more optical characteristics of these nanotubes, the modifications of which are evaluated in the presence of the target product. In addition, a method is provided for manufacturing and preparing such a component or device, and a detection method using them, as well as a post-manufacture preparation method comprising a specific functionalization for different target products starting from the same type of pluripotent generic component. Also provided is a family of PFO-based functionalization polymers.

  • Patent number: 9568671
    Abstract: A photonic component is provided including at least one linear optical waveguide, of which an active portion is surrounded over all or part of its periphery by a grouping of one or more essentially semiconducting nanotubes. These nanotubes interact with their exterior environment in an active zone extending on either side of the optical waveguide, to thus induce an optical coupling between an electrical or optical signal applied to the nanotubes and on the other hand an optical signal in the active portion of the waveguide. Such a component can carry out bipolar electro-optical functions as light source, or modulator or detector, inside the optical guide, for example with an electro-optical coupling between on the one hand an electrical signal applied between the electrodes, and on the other hand an optical signal emitted or modified in the active portion of the optical waveguide towards the remainder of the optical guide.
