A waveguide probe for the detection of pathogens in a sample which comprises a laser, a first and a second tubes that converge at a point to form a proximal end. A magnet is positioned in the end to configure to focus paramagnetic microspheres attached to antigen/antibody/optically labeled antibody complexes in the field of view. The proximal end is polished to form an aperture.

Tapered tubular optical waveguide probe for magnetic focusing immunosensors

A magnetic focusing immunosensor for the detection of pathogens comprising a laser, an exciting fiber and a collecting fiber, a fiber optic magnetic probe in communication with the collecting and exciting fibers and means for detecting, collecting and measuring fluorescent signals in communication with the collecting fiber. The probe and the collecting and exciting fibers are configured to focus paramagnetic microspheres attached to antigen/antibody/optically labeled complexes in a predetermined pattern in the field of view of the collecting fiber while blocking background interference.
