Top 10 Atomic Force Microscopy Companies Redefining Surface Science
Author : Aparna | September 4, 2024
Atomic Force Microscopy (AFM) is an advanced imaging technique that has revolutionized the study of surfaces at the nanoscale. By employing a sharp probe that scans the surface of a sample, AFM allows scientists to visualize and measure the topography and properties of materials with remarkable precision, often down to the atomic level. According to Kings Research, the global atomic force microscopy market is estimated to hit a valuation of USD 1,048.9 million by 2031. This blog discusses the top 10 companies involved in this niche based on their innovative product offerings and global presence.
What is atomic force microscopy?
Atomic force microscopy machine is an advanced imaging technique within the realm of scanning probe microscopy (SPM). Introduced in 1986 by Gerd Binnig, Christoph Quate, and Wolfgang Gerber, AFM has become a crucial instrument in nanotechnology and materials science.
The technique involves scanning a sharp probe, or tip, over a sample's surface to measure the forces between the tip and the surface at the atomic level. This interaction produces high-resolution three-dimensional topographical maps, revealing details on the nanometer scale, often with resolutions exceeding 1 nanometer.
What is the principle of atomic force microscopy?
Atomic Force Microscopy (AFM) is based on an intermolecular force measurement between a pointed probe and a sample surface. In essence, AFM utilizes a cantilever with a sharp tip that scans the surface of a sample.
The approach of the tip toward the surface induces intermolecular forces—van der Waals forces, electrostatic forces, and mechanical forces—that give rise to cantilever bending. A laser beam is employed to detect cantilever bending by reflecting the beam of the cantilever and onto a photodetector surface. This provides a direct measurement of the tip micromovement as a function of the features of the surface.
AFMs can operate in various modes, such as contact mode, where the tip makes direct contact with the surface, and non-contact mode, where the tip hovers above the surface without making contact. In contact mode, the deflection of the cantilever is continually recorded in real-time, and feedback is utilized to allow the system to maintain a constant force applied to the sample by the tip. This feedback loop accomplishes high-resolution topographical imaging at the nanoscale and can achieve resolution measurements down to fractions of a nanometer.
