Scanning tunnelling microscopy of biomacromolecules
Journal of Microscopy, 1988SUMMARYWhen imaging biomacromolecules with a STM, coating of specimens with a conductive layer is a convenient preparation method which provides a good rate of success. Utilizing evaporated platinum/carbon as a coating film we have investigated two biomacromolecules of very different appearance.

Scanning tunnelling microscopy in biotechnology
Trends in Biotechnology, 1990The scanning tunnelling microscope (STM) is capable of atomic resolution of highly conductive materials. Whether biological molecules can be visualized to the same extent remains an open question, but remarkable progress in the past year confirms the possibility of seeing the fine structure of nucleic acids, proteins, membranes and viruses, and ...

Scanning tunnelling microscopy
Contemporary Physics, 1991Abstract Since its inception in 1982, the Scanning Tunnelling Microscope (STM) has had an increasing importance in the examination of surfaces at an atomic level in real space. The unique performance of this imaging technique stems from the quantum tunnelling process employed.

Abstract : Scanning tunneling microscopy (STM) has been used to image and modify the surfaces of III-V, II-VI and group IV semiconductors. A tip-simulator based on a photocode was developed. The simulator allows the development of ultra- sensitive electronics for controlling STM tip movement.

Scanning Tunnelling Microscopy
1990Since its introduction by Binnig et al.,(1) the Scanning Tunnelling Microscope (STM) has engendered much excitement among surface scientists, not only for the atomically resolved surface topography it can achieve, but also for the range of surface spectroscopy possible.

STM is a surface microscope with extremely high spatial resolution, which enables us to see atoms on surfaces. When a sharp metal needle is located at a very proximate distance (~1 nm) from the sample surface (left panel in Fig. 97.1), tiny amount of electrical flow, called a tunneling current, is induced between them. Since the current is so sensitive

Scanning Tunnelling Microscopy
1992The scanning tunnelling microscope, or STM, has emerged over the last few years as a fascinating new technique for examining conducting solid surfaces with high resolution [10.1–5]. A sharpened metal wire is brought close enough to the surface so that the electrons “tunnel” across the narrow gap (0.5–1.5 nm).
