Linear electron resonator

The linear electron resonator is constructed on a Ag(111) surface at 6 K substrate temperature. The silver cluster at the middle (at the initial part of the movie) is produced by gently crashing the STM-tip into the substrate. The cluster is then broken into smaller clusters using the STM-tip. The individual silver atoms are extracted from the cluster on an atom-by-atom basis. These extracted atoms are repositioned by using the STM lateral manipulation procedure. The atoms are aligned along [110] surface directions. The distance between the two nearest silver atoms is 1.732 nm (6 atom distances apart). This electron resonator is 25 nm long, 12 nm wide, and consists of 30 silver atoms.

Researchers led by Hong Koo Kim, co-director of the Institute of NanoScience and Engineering at the University of Pittsburgh, have developed a new technology that may revolutionize optics and fields like imaging, spectroscopy, and information technology.

NanoMRI microscope

IBM Research scientists, in collaboration with the Center for Probing the Nanoscale at Stanford University, have demonstrated magnetic resonance imaging (MRI) with volume resolution 100 million times finer than conventional MRI. This result, published in the Proceedings of the National Academy of Sciences (PNAS), signals a significant step forward in tools for molecular biology and nanotechnology by offering the ability to study complex 3D structures at the nanoscale. By extending MRI to such fine resolution, the scientists have created a microscope that, with further development, may ultimately be powerful enough to unravel the structure and interactions of proteins, paving the way for new advances in personalized healthcare and targeted medicine. This achievement stands to impact the study of materials from proteins to integrated circuits for which a detailed understanding of atomic structure is essential.

Scanning Probe Microscopes (SPM) include Atomic Force Microscopes (AFM) and Scanning Tunneling Microscopes (STM or STEM). They are the only instruments in widespread use that can actually 'see' single atoms! You can skim this webpage quickly to learn the general concepts of SPM's, or you can read carefully and almost be ready to operate one!
