Preparation of a Micropatterned Rigid-Soft Composite Substrate for Probing Cellular Rigidity Sensing
2014Substrate rigidity has been recognized as an important property that affects cellular physiology and functions. While the phenomenon has been well recognized, understanding the underlying mechanism may be greatly facilitated by creating a microenvironment with designed rigidity patterns.

Traction forces and rigidity sensing of adherent cells
2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009This article is a concise review of our efforts in understanding the biological functions of traction forces, particularly in relation to the detection of rigidity of adhesive materials by fibroblasts.

Rigid Rod-Based FRET Probes for Membrane Sensing Applications
The Journal of Physical Chemistry B, 2016Oligospirothioketal (OSTK) rods are presented as an adjustable scaffold for optical membrane probes. The OSTK rods are readily incorporated into lipid bilayers due to their hydrophobic backbones. Because of their high length-over-diameter aspect ratio, only a minimal disturbance of the lipid bilayer is caused.

Sensing, Threading, Orienting, and Cutting Polymers with Rigid-Rod Pores
Journal of Receptors and Signal Transduction, 2006This short review describes synthetic pores that are made from rigid-rod molecules and can bind oligo-and polymers such as polyacetylenes, p-oligophenyls, terpenoids, polypeptides, polysaccharides, and oligonucleotides. The spotlight is on recent breakthroughs to image the longtime elusive pore-polymer host-guest complexes as single giant ...

Sensing of substratum rigidity and directional migration by fast-crawling cells
Physical Review E, 2018Living cells sense the mechanical properties of their surrounding environment and respond accordingly. Crawling cells detect the rigidity of their substratum and migrate in certain directions. They can be classified into two categories: slow-moving and fast-moving cell types. Slow-moving cell types, such as fibroblasts, smooth muscle cells, mesenchymal

Semi-Rigid Registration of Remote Sensing Airborne Scanner Images
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006This communication addresses the problem of automatic registration of raw images issued from an airborne multispectral imaging scanner with the aid of reference ortho-images available by classical aerial photography. We develop the proposed model, which accounts for a scan line shift process, in order to compensate for the roll motion of the aircraft ...

Sensing and recognition of rigid objects using structured light
IEEE Control Systems Magazine, 1988Word directed toward the development of a vision system for bin picking of rigid 3D objects is reported. Any such system must have components for sensing, feature extraction, modeling, and matching. A structured light system which attempts to deliver a rich 2/sup 1///sub 2/D representation of the scene is described.

Traction forces and rigidity sensing regulate cell functions
Soft Matter, 2008Increasing evidence suggests that mechanical cues inherent to the extracellular matrix may be as important as its chemical nature in regulating cell behavior. Here, the response of cells to the mechanical properties of the substrate is examined by culturing 3T3 fibroblastic cells and epithelial cells on surfaces composed of a dense array of flexible ...

in a sense such that the solutions of one of these equations are in one-to-one correspondence to the solutions of the other equation. A positively stable in the Lyapunov sense ω-periodic solution π(t) to Eq. (3) corresponds to a positively stable [with respect to condition (2)] ω-periodic solution ψ(t) to Eq. (1) and vice versa.

Rigid carbon–polymer biocomposites for electrochemical sensing. A review
The Analyst, 1996This paper reviews the use of biocomposite materials in the construction of amperometric biosensors. These rigid composites are formed by dispersing graphite particles in assorted polymers (especially epoxy resins). These composites are bulk-modified biologically (adding enzymes and cofactors) and chemically (blending mediators and catalysts).
