THE EVALUATION OF TOPOGRAPHY BORRELIA BURGDORFERI BY ATOMIC FORCE MICROSCOPE (AFM)

Characterization of Metallic Nanowires by Combining Atomic Force Microscope (AFM) and Scanning Electron Microscope (SEM)

A new experimental method is introduced in order to characterize the mechanical properties of metallic nanowires. An accurate mechanical characterization of nanowires requires simultaneous imaging using scanning electron microscope (SEM) and mechanical testing with an atomic force microscope (AFM). In this study, an AFM is located inside an SEM chamber in order to establish the visibility of th...

Force 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....

Simulations of the Frequency Modulated - Atomic Force Microscope (FM-AFM) Nonlinear Control System

The Frequency Modulated Atomic Force Microscope (FM-AFM) is a powerful tool to perform surface investigation with true atomic resolution. The control system of the FM-AFM must keep constant both the frequency and amplitude of oscillation of the microcantilever during the scanning process of the sample. However, tip and sample interaction forces cause modulations in the microcantilever motion. A...

Force-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...
