The atomic force microscope as a mechano–electrochemical pen
We demonstrate a method that allows the controlled writing of metallic patterns on the nanometer scale using the tip of an atomic force microscope (AFM) as a "mechano-electrochemical pen". In contrast to previous experiments, no voltage is applied between the AFM tip and the sample surface. Instead, a passivated sample surface is activated locally due to lateral forces between the AFM tip and t...
متن کاملForce Spectroscopy with the Atomic Force Microscope
Introduction and Review Atomic Force Microscope (AFM) Spectroscopy is an AFM based technique to measure, and sometimes control the polarity and strength of the interaction between the AFM tip and the sample. Although the tip-sample interaction may be studied in terms of the energy, the quantity that is measured first is always the tip-sample force, and thus the nomenclature: force spectroscopy....
متن کاملAtomic Force Microscope as a tool for nanomanipulation
An atomic force microscope (AFM) based system has been built for the manipulation of materials at the nanometer scale. The AFM is combined with an inverse optical microscope and an UV-laser microbeam system for photoablation. The actuators of the AFM are controlled using a digital signal processor. Real-time routines and a graphical user interface have been programmed for high resolution imagin...
متن کاملHydration force in the atomic force microscope: A computational study.
Using a hard sphere model and numerical calculations, the effect of the hydration force between a conical tip and a flat surface in the atomic force microscope (AFM) is examined. The numerical results show that the hydration force remains oscillatory, even down to a tip apex of a single water molecule, but its lateral extent is limited to a size of a few water molecules. In general, the contrib...
متن کاملForce-feedback High-speed Atomic Force Microscope
High-speed atomic force microscopy (HSAFM) has enabled researchers to view the nanometer-scale dynamic behavior of individual biological and bio-relevant molecules at a molecular-level resolution under physiologically relevant time scales, which is the realization of a dream in life sciences. These high-speed imaging applications now extend to the cellular/bacterial systems with the use of a sm...
