Automated Dielectrophoretic Tweezers-Based Force Spectroscopy System in a Microfluidic Device
Sensors, 2017 We reported an automated dielectrophoretic (DEP) tweezers-based force spectroscopy system to examine intermolecular weak binding interactions, which consists of three components: (1) interdigitated electrodes and micro-sized polystyrene particles used as

Measuring cell adhesion forces with the atomic force microscope at the molecular level [PDF]
, 2002 In the past 25 years many techniques have been developed to characterize cell adhesion and to quantify adhesion forces. Atomic force microscopy (AFM) has been used to measure forces in the pico-newton range, an experimental technique known as force ...

Raman Topography and Strain Uniformity of Large-Area Epitaxial Graphene
, 2008 We report results from two-dimensional Raman spectroscopy studies of large-area epitaxial graphene grown on SiC. Our work reveals unexpectedly large variation in Raman peak position across the sample resulting from inhomogeneity in the strain of the ...

Cryo-EM structure of the CFA/I pilus rod
IUCrJ, 2019 Enterotoxigenic Escherichia coli (ETEC) are common agents of diarrhea for travelers and a major cause of mortality in children in developing countries. To attach to intestinal cells ETEC express colonization factors, among them CFA/I, which are the most ...

Equilibrium binding energies from fluctuation theorems and force spectroscopy simulations
, 2016 Brownian dynamics simulations are used to study the detachment of a particle from a substrate. Although the model is simple and generic, we attempt to map its energy, length and time scales onto a specific experimental system, namely a bead that is ...
