Dual Actuation for High Speed Atomic Force Microscopy
In atomic force microscopy (AFM) the imaging speed is strongly limited by the bandwidth of the feedback loop that controls the interaction between the measurement tip and the sample. A significant increase in closed-loop bandwidth can be achieved by combining a long-range, low-bandwidth actuator with a short-range, high-bandwidth actuator, forming a dual actuated system. This contribution discu...
متن کاملHigh-speed atomic force microscopy.
High-speed atomic force microscopy (HS-AFM) has been developed as a nano-dynamics visualization technique. This microscopy permits direct observation of structure dynamics and dynamic processes of biological molecules in physiological solutions, at a subsecond to sub-100 ms temporal resolution and an ∼2 nm lateral and a 0.1 nm vertical resolution. Importantly, tip-sample interactions do not dis...
متن کاملComponents for high speed atomic force microscopy.
Many applications in materials science, life science and process control would benefit from atomic force microscopes (AFM) with higher scan speeds. To achieve this, the performance of many of the AFM components has to be increased. In this work, we focus on the cantilever sensor, the scanning unit and the data acquisition. We manufactured 10 microm wide cantilevers which combine high resonance ...
متن کاملStudying biological membranes with extended range high-speed atomic force microscopy
High-speed atomic force microscopy has proven to be a valuable tool for the study of biomolecular systems at the nanoscale. Expanding its application to larger biological specimens such as membranes or cells has, however, proven difficult, often requiring fundamental changes in the AFM instrument. Here we show a way to utilize conventional AFM instrumentation with minor alterations to perform h...
