Atomic Force Microscopy
Atomic force microscopy is a high-resolution scanning probe technique that images and measures surfaces at the atomic level by detecting forces between a sharp probe and the sample. This method allows for three-dimensional visualization and even manipulation of materials at the nanoscale, making it essential for advancing fields like materials science and biotechnology where traditional microscopes fall short.

In 1990, IBM researchers used atomic force microscopy to precisely arrange 35 individual xenon atoms on a nickel surface to spell out the letters 'IBM', demonstrating the technique's ability to manipulate matter at the atomic scale and inspiring breakthroughs in nanotechnology. This experiment, conducted by a team led by Donald Eigler, was the first time humans directly controlled atoms, opening doors to potential applications in quantum computing and molecular machines.
