Introduction to Park Systems and Atomic Force Microscopy
Park Systems, headquartered in Suwon, South Korea, is a global leader in atomic force microscopy (AFM). Since its inception, the company has focused on advancing AFM technology to provide unparalleled resolution, accuracy, and ease of use. But what does the Korean company Park Systems do in practical terms? They essentially provide the tools – incredibly precise microscopes – that allow scientists and engineers to “see” and manipulate matter at the atomic and molecular level. This capability is crucial for understanding and developing new materials, improving manufacturing processes, and unraveling the complexities of biological systems.
Understanding Atomic Force Microscopy (AFM)
AFM is a technique that allows scientists to image surfaces with atomic resolution. Unlike traditional optical microscopes, AFM doesn’t rely on light. Instead, it uses a sharp tip, often just a few atoms wide, to scan the surface of a sample. This tip is attached to a cantilever, a small beam that bends or deflects as the tip interacts with the surface. The amount of bending is measured and used to create an image of the surface topography. Different modes of AFM operation allow for mapping of various properties, including:
- Topography: Mapping the surface height.
- Mechanical Properties: Measuring stiffness, adhesion, and friction.
- Electrical Properties: Mapping conductivity and charge distribution.
- Magnetic Properties: Imaging magnetic domains.
Park Systems’ Innovations in AFM
Park Systems has consistently pushed the boundaries of AFM technology through its innovative designs and features. Some key innovations include:
- True Non-Contact™ Mode: This mode minimizes sample damage and tip wear by oscillating the cantilever at its resonant frequency and avoiding direct contact with the surface.
