1 answer
The needle in a scanning tunneling microscope is typically on the nanometer scale, ranging from 1 to 10 nanometers in diameter. Its sharp tip allows for atomic-scale resolution during imaging by detecting the tunneling current between the tip and the surface being scanned.

The scanning tunneling microscope allows scientists to see individual atoms on a surface by detecting the tunneling current between the microscope tip and the sample. The one-angstrom microscope is a hypothetical concept that would potentially allow scientists to visualize atomic details with even higher resolution.

A scanning probe microscope is a type of microscope that uses a physical probe to scan the surface of a sample to create images with very high resolution. It provides detailed information about the topography and properties of the sample at the nanoscale level. Examples of scanning probe microscopes include atomic force microscopes and scanning tunneling microscopes.

The scanning tunneling microscope (STM) is typically used for imaging surfaces of materials at the atomic level, regardless of whether the sample is alive or dead. The STM works by scanning a sharp metal tip over the sample surface and detecting the tunneling current between the tip and the surface, allowing for atomic-scale resolution imaging. It is commonly used in both materials science and nanotechnology research.

It depends on the power of the microscope an the skill you have in preparing slides.
Around 150x, good slide prepartion becomes crucial.
a quick search on google reveals many guides to building your own Scanning Tunneling Microscope (STM). If you do attempt such a feat the following books might be helpful;
- Lewis et al. "Student Scanning Tunneling Microscope" Am. J. Phys, 59(1), 38-42. (1991)
- Pohl, "Some Design Criteria in Scanning Tunneling Microscopy", IBM J. Res. Dev., 30(4), 417-427, (1986)
- Binning & Rohrer, "Scanning Tunneling Microscopy" IBM J. Res. Dev., 30(4), 355-369, (1986)
- Binning & Smith, "Single-Tube Three-Dimensional Scanner for Scanning Tunneling Microscopy", Rev. Sci. Instrum. 57(8), 1688-1689, (1986)
- Sears et al., "A Scanning Tunneling Microscope for Undergraduate Laboratories", Computers in Physics Jul/Aug, 427-430, (1990)
I believe that a home made STM can be made for about $100 and should provide atomic resolution.

An electron microscope, particularly a transmission electron microscope, can be used to visualize DNA as its electrons have a shorter wavelength enabling higher resolution. For botulinum toxin, a scanning electron microscope can also be used to visualize its structure due to its high magnification capabilities.

A scanning probe microscope uses a physical probe to scan the surface of a sample, detecting variations in properties such as force, current, or tunneling. In contrast, an electron microscope uses a beam of electrons to image the sample at high magnification, providing detailed information on its morphology and composition.

This statement is incorrect. John Dalton was a British scientist known for developing the atomic theory in the early 19th century. The scanning tunneling microscope was invented much later, in 1981 by Gerd Binnig and Heinrich Rohrer.

A scanning tunneling microscope is a powerful tool used in nanotechnology to observe surfaces at atomic level. It works by scanning a sharp metal tip across a surface, measuring the current that flows due to quantum tunneling between the tip and the surface. This allows for high-resolution imaging and manipulation of individual atoms and molecules.

Yes, scanning tunneling microscopes (STMs) can be used to see individual atoms on a surface. By measuring the current that flows between a sharp tip and the sample surface, STMs can create atomic-scale images with high resolution. This technology has been crucial in advancing our understanding of atomic structures and phenomena on the nanoscale.

"View" may not be exactly the right word. A Scanning Tunneling Microscope can be used to gather data that a computer can turn into an image, but they're not really "seeing" the individual atoms directly.
