What is a Scanning probe microscope?

The Scanning Probe Microscope (SPM) is an advanced, high-precision instrument used to observe and measure the fine details of surfaces and material properties. It enables atomic-level analysis and can measure surface height with nanometer precision. The microscope scans the surface using a probe that makes contact with the material, providing high-resolution data on the shape and characteristics of the surface. It plays a critical role in fields like nanotechnology, materials science, and biology.

SPM includes several techniques, such as Atomic Force Microscopy (AFM) and Scanning Tunneling Microscopy (STM), which allow for the measurement of various physical properties in different modes. This allows for the acquisition of information on surface shape, conductivity, mechanical properties, and more at the nanoscale.

Application of Scanning probe microscope

１．Nanotechnology Research
SPM is widely used in nanotechnology to study the structure and properties of materials at the nanoscale. For instance, it plays a key role in analyzing the surface structures of nanomaterials, the shape of nanoparticles, and the behavior of self-assembling molecules.
２．Semiconductor Quality Control
In semiconductor manufacturing, SPM is used to measure fine surface structures, check for defects, and verify surface uniformity. It provides detailed information about the microstructures, helping ensure high-quality production.
３．Applications in the Biological Field
SPM is used to study the surface characteristics and interactions of biological molecules. For example, it can observe the surface shape of cell membranes or protein interactions at the nanoscale, contributing to medical research and biological analysis.
