Imaging viscoelastic properties of live cells by AFM: power-law rheology on the nanoscale.
We developed force clamp force mapping (FCFM), an atomic force microscopy (AFM) technique for measuring the viscoelastic creep behavior of live cells with sub-micrometer spatial resolution. FCFM combines force-distance curves with an added force clamp phase during tip-sample contact. From the creep behavior measured during the force clamp phase, quantitative viscoelastic sample properties are e...
متن کامل3D force and displacement sensor for SFA and AFM measurements.
A new device has been designed, and a prototype built and tested, that can simultaneously measure the displacements and/or the components of a force in three orthogonal directions. The "3D sensor" consists of four or eight strain gauges attached to the four arms of a single cross-shaped force-measuring cantilever spring. Finite element modeling (FEM) was performed to optimize the design configu...
متن کاملStatistical Analysis of Single-Molecule AFM Force Spectroscopy Curves
We develop a statistical framework for the quantitative characterization and analysis of force-extension curves obtained from single-molecule force spectroscopy (SMFS) measurements. We apply this methodology to force-extension data obtained for elastinlike polypeptides (ELPs) with precisely engineered molecular architectures, where we demonstrate that our approach enables SMFS to be used to stu...
متن کاملProbing Nanoscale Heat and Force Interactions Using Atomic Force Microscopes (afm)
Many devices and instruments such as magnetic hard disk drives and atomic force microscopes (AFM) rely on the stable operation of their small probing heads at nanoscale gaps. Due to the small scale of the probing heads, the force interactions (Casimir force and electrostatic force) between the small probes and the surrounding become more significant. The local heating caused by read/write elect...
متن کاملMeasuring bacterial cells size with AFM
Atomic Force Microscopy (AFM) can be used to obtain high-resolution topographical images of bacteria revealing surface details and cell integrity. During scanning however, the interactions between the AFM probe and the membrane results in distortion of the images. Such distortions or artifacts are the result of geometrical effects related to bacterial cell height, specimen curvature and the AFM...
