Polymer Characterization with the Atomic Force Microscope
Atomic force microscopy is a powerful characterization tool for polymer science, capable of revealing surface structures with superior spatial resolution [1]. The universal character of repulsive forces between the tip and the sample, which are employed for surface analysis in AFM, enables examination of even single polymer molecules without disturbance of their integrity [2]. Being initially d...
متن کاملProbing single biomolecules with atomic force microscopy.
During the last years, atomic force microscopy (AFM) has developed from a microscopy tool for solid-state surface science toward a method employed in many scientific disciplines, such as biology, for investigating individual molecules on a nanometer scale. This article describes the current status of the imaging possibilities of AFM on RNA, IgG, and gold-labeled cell adhesion proteoglycans, as ...
متن کاملSingle-Cell Elastography: Probing for Disease with the Atomic Force Microscope
The atomic force microscope (AFM) is emerging as a powerful tool in cell biology. Originally developed for high-resolution imaging purposes, the AFM also has unique capabilities as a nano-indenter to probe the dynamic viscoelastic material properties of living cells in culture. In particular, AFM elastography combines imaging and indentation modalities to map the spatial distribution of cell me...
متن کاملProbing Molecular Relaxation on Polymer Surfaces with Friction Force Microscopy
The scan-velocity dependence of friction force microscopy (FFM) is characterized on gelatin films and related to the rate dependence of molecular relaxations. For selected scanning-parameter values the velocity dependence of frictional force is affected by the measurement process, because of energy imparted to the tip-sample contact region: a peak in the friction-velocity relationship, attribut...
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....
