WaveMode: Simple and Fast Imaging

This technical note provides a comprehensive overview of Nanosurf's WaveMode technology. It explains how WaveMode, powered by CleanDrive photothermal excitation, achieves gentle high-speed off-resonance imaging, minimizing lateral forces and enhancing resolution. It details the operational advantages of WaveMode, including its ability to acquire cantilever trajectories by oscillating the cantilever without moving the holder or sample and reconstruct force-distance curves from these measurements, significantly increasing imaging speed, accuracy, and the amount of quantitative information available.

The technical note also covers the practical aspects of using WaveMode, such as the setup and calibration process, the selection of appropriate cantilevers, and the configuration of imaging parameters using the Nanosurf Studio software.
