1. Apparatus for detecting biofilm in a fluid system comprising;

  • a wall portion having an outside surface outside the fluid flow and an inside surface in contact with the fluid flow and being transparent to excitation and emitted light;

    a biofilm target substrate integral with the inside surface in contact with fluid in the fluid system;

    an optical fiber sensor in optical contact with the outside surface and having at least one fiber (excitation fiber) for sending excitation light through the wall portion to the biofilm substrate and at least one fiber for receiving emitted autofluorescence from the biofilm caused by the excitation light (emission fiber).
