Abstract: Adhesion can be quantified by measuring the distance between the interacting surfaces. Reflection interference contrast microscopy (RICM), with its ability to measure inter-surface distances under water with nanometric precision and milliseconds time resolution, is ideally suited to studying the dynamics of adhesion in soft systems. Recent technical developments, which include innovative image analysis and the use of multi-coloured illumination, have led to renewed interest in this technique. Unambiguous quantitative measurements have been achieved for colloidal beads and model membranes, thus revealing new insights and applications. Quantification of data from cells shows exciting prospects. Herein, we review the basic principles and recent developments of RICM applied to studies of dynamical adhesion processes in soft matter and cell biology and provide practical hints to potential users.

Oleoplaning droplets on lubricated surfaces
Dan Daniel,Jaakko V. I. Timonen,Jaakko V. I. Timonen,Ruoping Li,Seneca J. Velling,Joanna Aizenberg,Joanna Aizenberg +6 more
TL;DR: In this paper, the authors show that for a moving droplet, the film thickness follows the Landau-Levich-Derjaguin law and the droplet is therefore oleoplaning with minimal dissipative force and no contact line pinning.

Ptychography – a label free, high-contrast imaging technique for live cells using quantitative phase information
TL;DR: The biological application of a, label-free, high contrast microscopy technique known as ptychography, in which the image producing step is transferred from the microscope lens to a high-speed phase retrieval algorithm, which is suitable for downstream automated cell segmentation and analysis.
Physics of cell adhesion: some lessons from cell-mimetic systems
TL;DR: The basic physical rules governing the physics of cell adhesion learned by studying cell-mimetic systems are reviewed and the importance of these rules in the context of cellular systems is demonstrated.
Characterisation of hydrogels: Linking the nano to the microscale.
TL;DR: This review presents the main characterisation methods providing both qualitative and quantitative information of the structures and compositions of hydrogel, and aims at quantifying swelling, mechanical strength, mesh size, bound and free water content, pore structure, chemical composition, strength of chemical bonds and mechanical strength.

Elastic Properties of Lipid Bilayers: Theory and Possible Experiments
TL;DR: A theory of the elasticity of lipid bilayers is proposed and it is argued that in the case of vesicles (= closed bilayer films) the only elasticity controlling nonspherical shapes is that of curvature.

Focal Contacts as Mechanosensors Externally Applied Local Mechanical Force Induces Growth of Focal Contacts by an Mdia1-Dependent and Rock-Independent Mechanism
Daniel Riveline,Daniel Riveline,Eli Zamir,Nathalie Q. Balaban,Ulrich S. Schwarz,Toshimasa Ishizaki,Shuh Narumiya,Zvi Kam,Benjamin Geiger,Alexander D. Bershadsky +9 more
TL;DR: Experiments show that integrin-containing focal complexes behave as individual mechanosensors exhibiting directional assembly in response to local force, and that external tension force bypasses the requirement for ROCK-mediated myosin II contractility in the induction of focal contacts.
The mechanism of adhesion of cells to glass. a study by interference reflection microscopy.
TL;DR: Evidence is presented that the mechanism of cell adhesion does not involve calcium atoms binding cells to substrate by combining with carboxyl groups on cell surface, substrate, and with a cement substance, and that there is no extracellular material between cell and glass in the adhesions.

TL;DR: The measured spatial dependence of the potential is consistent with the screened Coulomb repulsion expected from the Derjaguin-Landau-Verwey-Overbeek theory of colloidal interactions.
