What Is Atomic Force Microscopy? Atomic force microscopy (AFM ... In polymer research, AFM detects the molecular stiffness of hyperbranched macromolecules, quantifies single polymer chain elongation, ...

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller features, and electron microscopy resolves small structures, but samples ...

Atomic force microscopy (AFM) has been emerging as ... elasticity Aldosterone increased both apical cell surface and apical cell stiffness significantly, while transendothelial permeability ...

Current optical and electron microscopy imaging techniques are not suited for measuring the dynamic characteristics of living microorganisms at tiny scales due to complex sample preparation methods or ...

cell stiffness and cell membranes; assessing cell adhesion; studying biological samples in vitro, in situ, and in vivo without preparing samples. Atomic force microscopy uses aqueous or nonaqueous ...

In addition, molecular interactions control the way that cells communicate with each other ... Within a decade, this unconventional microscope has evolved into a multifunctional toolbox.

Without the need for a current, such an "atomic force microscope" (AFM) could reveal the structure of nonconductive materials such as proteins, organelles, and whole cells. Immediately thereafter, the ...

Living-cell atomic force microscopy study of clinical drugs and ... increased both apical cell surface and apical cell stiffness significantly, while transendothelial permeability remained ...

Atomic force microscopy (AFM) is a technique originally ... Japan. During E. coli cell division, the researchers observed increased mechanical stiffening of the cell division site.

Escherichia coli bacteria imaged by high-speed inline force mapping and fluorescence microscopy. Simultaneous topography and elastic modulus maps show a stiffening of the division site.
