Applications of Atomic Force Microscopy
Atomic Force Microscopy (AFM) is a versatile tool used for detailed surface imaging and analysis. It offers high-resolution imaging for both dry and liquid samples, making it invaluable for biological studies, nucleic acid research, and mechanical property analysis. AFM’s applications range from real-time cell biology observations to nanofabrication and defect detection in materials, highlighting its…

Atomic Force Microscopy
Introduction to Atomic Force Microscopy (AFM) Atomic force microscopy (AFM) is a cutting-edge member of the microscopic techniques known collectively as scanning probe microscopy (SPM). The underlying principles of SPM are markedly distinct from those of light and electron microscopy. SPM methods are used to study the surface properties of materials by scanning an extremely fine probe over the specimen surface. This relatively recent technique emerged in 1981 when Gerd Binnig and Heinrich Rohrer developed the first working SPM, specifically the scanning tunneling microscope (STM).

Atomic Force Microscopy (AFM)
Atomic Force Microscopy (AFM) is a powerful imaging technique used to visualize and manipulate materials at the nanoscale. By scanning a sharp probe over a sample surface, AFM measures the interaction forces between the probe and the sample, providing high-resolution images and information about surface properties. This study note delves into the principles, instrumentation, operational…
