Microscope and Microscopy Supplies

AFM microscopy requires specialized cantilevers and probes matched to your imaging mode and sample type. Carbon nanotube tips provide high-resolution imaging with wear resistance, while diamond-coated variants enable mechanical testing. MAC Mode compatible probes feature paramagnetic coatings for precise oscillation control. You'll also need calibration samples, appropriate mounting substrates, and potentially environmental control accessories depending on whether you're imaging in air, liquid, or controlled atmospheres. Consumables include cleaning supplies and probe storage solutions.

Traditional optical microscopes comprise eyepiece, objective lenses, stage, illumination source, condenser, focus knobs, arm, base, diaphragm, nosepiece, and tube. For atomic force microscopes, key components include the cantilever and tip, piezoelectric scanner, laser and photodetector assembly, feedback control electronics, sample stage, vibration isolation system, environmental control chamber, software interface, approach mechanism, scanner head, base frame, and control electronics. These work together to achieve atomic-scale resolution imaging.

AFM microscopy enables visualization of DNA strands, proteins, cell membranes, polymers, nanoparticles, thin films, semiconductor surfaces, battery electrodes, catalysts, graphene sheets, carbon nanotubes, viruses, bacteria, tissue samples, drug formulations, molecular monolayers, crystal structures, surface defects, polymer phase transitions, electrochemical reactions, molecular electronics, biomolecular interactions, nanowires, quantum dots, colloidal particles, lipid bilayers, antibody-antigen complexes, enzyme activity, surface roughness features, coatings, and material interfaces. The technology spans biological to materials science applications.

Molecular Imaging offers multiple cantilever types optimized for specific imaging modes including contact mode for hard materials, tapping mode for soft biological samples, and MAC Mode for precise oscillation control with paramagnetic coating. Carbon nanotube tips provide superior resolution and wear resistance for high-aspect-ratio features. Specialized cantilevers support liquid imaging of biological samples like DNA and proteins, while diamond-coated variants enable indentation testing and mechanical characterization across nanotechnology and materials science applications.

For biological sample imaging, choose soft cantilevers with low spring constants to minimize sample deformation during scanning. Liquid-compatible probes are essential for imaging cells, proteins, and DNA in physiological conditions. Consider carbon nanotube tips for high-resolution imaging of biomolecular structures with minimal tip wear. MAC Mode compatible probes with paramagnetic coating offer precise oscillation control for delicate samples. Molecular Imaging's probe selection supports applications from individual protein imaging to live cell characterization in controlled environmental conditions.

AFM cantilevers require careful handling and storage to maintain tip sharpness and prevent contamination. Regular calibration using reference samples ensures accurate dimensional and force measurements. Inspect tips for wear or damage before each use, particularly after imaging hard materials. Replace cantilevers when tip radius increases beyond acceptable limits for your resolution requirements. Clean contaminated probes using appropriate solvents based on sample type. Store cantilevers in provided protective packaging in low-humidity environments. Periodic system calibration verifies scanner accuracy and maintains measurement traceability.
