Atomic force microscopy (AFM) is a very high-resolution type of scanning probe microscopy (SPM). AFM uses a microscale cantilever with a sharp tip to measure surface topologies. It scans the specimen by touching the tip to the surface and measuring deflections of the cantilever using a laser spot and photodiode. Either the cantilever or the specimen is mounted on a piezoelectric scanner that can move the sample in a raster motion with respect to the cantilever tip. As the tip is dragged across the surface, forces between tip and sample lead to a deflection of the flexible cantilever according to Hooke's law. This deflection is measured using a laser spot reflected from the top surface of the cantilever into an array of photodiodes.
Market Dynamics:
The growing demand for semiconductor devices, rising adoption of nanotechnology, and increasing investments in life sciences research have boosted the adoption of AFM across various end-use industries. However, high cost of atomic force microscopes impedes the market growth. On the other hand, technological advancements in AFM technology to meet the demands of emerging applications present numerous lucrative opportunities for market players. For instance, dynamic atomic force microscopy allows real-time imaging of chemical and physical processes at the nanoscale.
