Naked DNA Helicity Observed by Scanning Tunneling Microscopywith high resolution Scanning Tunneling Microscope (STM). Constant current and barrier height STM images show a clear evidence of the helicity of the DNA structure: pitch periodicity ranges between 25 and 34 Å while the average diameter is 20 Å. Molecular structure within a single helix turn is also

Scanning Probe Microscopy of Liquid-Solid Interfacesvariety of systems that can be studied: from iron corroding in salt water to selenium atoms in liquid nitrogen and from graphite covered with vacuum grease to proteins covered with oil. The technological and biological importance of liquid-solid interfaces has driven and will ensure rapid growth in this field.

Theory of tunneling from transition metal tipsthe current. For short distances a significant part of the total tunnel current flows directly via the tip d-orbitals. The theory is used to investigate the ‘barrier height’ of the clean surface. A corrugation of the Al(111)-surface is obtained in STM-theory, if a elastic deformation of the tip is taken into account.

Scanning Tunneling Optical Microscopy (Stom) of Silver Nanostructurestensity (photon maps) reveals a close relation to topographic features. The sharp spatial contrast, lack of significant polarity dependence, and the detection of fieid emission resonances in isochromat photon spectra favor inelastic tunneling as the dominant process.

Study of the Biocompatibility of Surgical Implant Materials at the Atomic and Molecular Level Using d bacterial promotion, is attached on Ti and V substrates, but is not biologically active on V, a non-biocompatible substance. We present STM images of the Ti oxide layer and of single and multiple Fn molecules shadowed with a conductive layer.
