Atomic Force Microscopy (AFM) Service

Creative Biostructure provides images with near-atomic resolution for measuring surface topography using the Atomic Force Microscopy (AFM) technology. The Atomic Force Microscope is applied to solve processing and materials problems in a wide range of technologies affecting the electronics, telecommunications, biomedical, chemical, automotive, aerospace, and energy industries.

Technical Abilities

  • Measurement:
    i. Topography (surface roughness, grain size, step height, etc.) at the angstrom scale
    ii. Mechanical properties (stiffness, etc.)
    iii. Electrical properties (capacitance, conductivity, etc.)
    iv. Thermal properties
    v. Magnetic properties
  • These properties can be measured either in air or with the specimen immersed in a liquid, depending on your requests.

  • Imaging:

    AFM images show critical information about surface features with unprecedented clarity, including 3D images and quantitative data analysis (such as feature sizes, surface roughness and area, and cross-section plots), integrated and interpreted in the context of your problem.

  • Manipulation:

    In manipulation, the forces between tip and sample can also be used to change the properties of the sample in a controlled way, for example, atomic manipulation, scanning probe lithography and local stimulation of cells.

As the cantilever is displaced via its interaction with the surface, the reflection of the laser beam will be displaced on the surface of the photodiode.Figure 1.
