Tapered tubular optical waveguide probe for magnetic focusing immunosensors

   
   

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.

Una punta de prueba de la guía de onda para la detección de patógeno en una muestra que abarca un laser, un primer y segundo tubos que convergen en un punto para formar un extremo próximo. Un imán se coloca en el extremo para configurar para enfocar las microesferas paramagnéticas unidas a los complejos etiquetados antigen/antibody/optically del anticuerpo en el campo visual. El extremo próximo se pule para formar una abertura.
