  • Publication number: 20130316368
    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.
