Used NANOSURF Atomic Force Microscope (AFM) #293770952 for sale

NANOSURF Atomic Force Microscope (AFM) is a high-resolution imaging instrument that utilizes a sharp probe to scan the surface of a sample, providing detailed topographical information on a nanometer scale. The AFM is a powerful tool widely used in various fields such as materials science, nanotechnology, biology, and biophysics for studying surface morphology, mechanical properties, and surface interactions at the nanoscale level. The core principle of AFM operation involves the use of a sharp probe, typically a cantilever with a sharp tip at the end, which interacts with the sample surface. As the probe scans the surface, it experiences intermolecular forces such as van der Waals, electrostatic, and chemical forces between the tip and the sample. These interactions cause the deflection of the cantilever, which is detected by a sensitive detector, allowing for the generation of a topographical map of the surface. NANOSURF AFM is equipped with advanced features that enhance its imaging capabilities and performance. One of the key features of NANOSURF AFM is its high-resolution imaging capability, which allows researchers to visualize surface features with exceptional clarity and detail at the nanoscale level. The AFM can achieve lateral resolution down to the sub-nanometer range, making it ideal for studying small features, such as nanoparticles, nanowires, and biomolecules. In addition to high-resolution imaging, NANOSURF AFM offers various imaging modes that cater to different sample types and research requirements. The most commonly used imaging modes include contact mode, tapping mode, and dynamic mode. In contact mode, the probe tip maintains constant contact with the sample surface, providing high-resolution topographical information. Tapping mode, on the other hand, involves oscillating the cantilever near its resonance frequency, which reduces tip-sample interaction forces, minimizing sample damage and extending probe longevity. Dynamic mode, also known as non-contact mode, operates at a higher oscillation amplitude, allowing for the measurement of sample properties such as adhesion and stiffness. Moreover, NANOSURF AFM is equipped with advanced force spectroscopy capabilities, enabling researchers to study mechanical properties of the sample, such as adhesion, stiffness, and elasticity. By applying a controlled force to the sample surface, researchers can measure the force-distance curve, providing insight into the mechanical properties of the material at the nanoscale level. NANOSURF AFM is also capable of performing various other functions, such as nanomanipulation, nanolithography, and electrical characterization. Nanomanipulation allows researchers to manipulate individual nanoparticles or biomolecules on the surface with high precision, enabling the assembly of nanostructures and the study of molecular interactions. Nanolithography involves using the AFM probe to pattern surfaces at the nanoscale, offering a versatile tool for creating nanostructures and devices. Additionally, the AFM can be used for electrical characterization by integrating electrical probes to measure conductivity, resistivity, and capacitance of the sample. In summary, NANOSURF AFM is a versatile and powerful instrument for high-resolution imaging and nanoscale characterization of materials and biological samples. With its advanced features, imaging modes, and capabilities for force spectroscopy and nanomanipulation, the AFM serves as an indispensable tool for researchers in various fields seeking to explore and understand the nanoworld.
