The potential of surface plasmon resonance-enhanced total internal reflection
microscopy for visualization of submicron particles has been demonstrated using
submicron-sized silicon rods as a test object. Submicron Si-rods were deposited onto the
surface of a plasmon-supporting gold film by sedimentation from suspension, and their
images were obtained using optical microscope with SPR excitation. Quality of images
obtained in this way was compared with images viewed from the prism side in the SPR
microscopy configuration. Specific features of light scattering from filiform objects are
discussed. The study was aimed at development of a novel type of SPR-based biosensor
relied upon direct count of biological species of interest (bacteria, viruses, large
biomolecular complexes).
