In this presentation, we describe about the high resolution imaging of flagellar filaments of a salmonella with a diameter of 25 nm by a photon scanning tunneling microscope (PSTM). In our PSTM system, we have used a metal coated fiber probe with a nanometric dielectric protrusion fabricated by indigenous technique developed by us. By using this probe, flagellar filaments could be imaged as having a full width at half maximum of 50 nm. Obtained images strongly depended on the separation of the sample and to the probe, and the diameter of the aperture polarization of the irradiated light.
