Abstract :
We present the biomolecular imaging by using a terahertz pulse apertureless near-field microscope (THz NFM) with a nanometer resolution. THz NFM provides THz spectral imaging as well as topography of the nanostructured sample surface. By scanning the probe over a single biomolecular nanoparticle, the THz images and the scattering spectra were obtained.
