Electrochemiluminescent immunosensor for detection of protein cancer biomarkers using carbon nanotube forests and [Ru-(bpy)(3)](2+)-doped silica nanoparticles

We report the first electrochemiluminescent immunosensor combining single-wall carbon nanotube forests with RuBPY-silica-secondary antibody nanoparticles for sensitive detection of cancer biomarker prostate specific antigen.
