Implication

Experimental study demonstrates ultra-high-speed atomic force microscopy imaging at over 1300 frames per second on collagen fibers, indicating rapid nanoscale scanning without causing specimen damage.

Key Points

Develop and validate high-speed contact-mode atomic force microscopy systems capable of capturing sub-second nanoscale processes and imaging large specimen areas rapidly.
Engineered a high-speed flexure stage instrument capable of video-rate imaging at 30 frames per second.
Developed an ultra-high-speed system combining a tuning fork scanner and flexure stage designed to exceed 1000 frames per second.
Imaged collagen fibres under ambient conditions at relative tip–specimen velocities of up to 200 mm s⁻¹ across tens of thousands of consecutive frames.
Achieved high-resolution imaging of collagen fibres at speeds reaching 1300 frames s⁻¹.
Recorded tens of thousands of consecutive frames in the same sample area at tip velocities up to 200 mm s⁻¹ without causing observable structural damage to the collagen fibres.
