• , there was little apparent imaging damage to the structure once the feedback gains were adjusted properly. Conclusion Imaging gently and quickly is a constant challenge in AFM. Small cantilevers are well suited to low-dissipation imaging, especially in multifrequency imaging modes, since the spring
