Abstract

A new miniature Surface Forces Apparatus (SFA Mark III) is described for measuring the forces between surfaces in vapors and liquids. The apparatus employs similar techniques to those used in current SFAs, but it is easier to operate and is generally more user-friendly. Four stages of increasingly sensitive distance controls replace the three control stages of previous apparatuses. The first three stages allow for rapid manual control of surface separation to within 10 A, while the fourth piezo-control stage has a sensitivity of better than 1 A. All four distance controls have been specially designed to produce perfectly linear displacements of the surfaces. In addition, the SFA Mk III is more robust, less susceptible to thermal drifts, easier to clean, and requires smaller quantities of liquid than conventional SFAs. The high performance of this new instrument is illustrated in the proceeding paper (Paper II) which describes the subtle effects of surface lattice mismatch on the oscillatory forces in water in the distance regime from 0 to 10 A.

Real-time intermembrane force measurements and imaging of lipid domain morphology during hemifusion

Journal Article Lee, Dong Woog ; Kristiansen, Kai ; Donaldson, Stephen H. ; ... - Nature Communications

Membrane fusion is the core process in membrane trafficking and is essential for cellular transport of proteins and other biomacromolecules. During protein-mediated membrane fusion, membrane proteins are often excluded from the membrane–membrane contact, indicating that local structural transformations in lipid domains play a major role. However, the rearrangements of lipid domains during fusion have not been thoroughly examined. Here using a newly developed Fluorescence Surface Forces Apparatus (FL-SFA), migration of liquid-disordered clusters and depletion of liquid-ordered domains at the membrane–membrane contact are imaged in real time during hemifusion of model lipid membranes, together with simultaneous force–distance and lipid membrane thicknessmore »« less

Temperature and time effects on the ``adhesion dynamics`` of poly(butyl methacrylate) (PBMA) surfaces

Journal Article Luengo, G ; Pan, J ; Heuberger, M ; ... - Langmuir

The authors present a surface force apparatus (SFA) study of the effects of time and loading-unloading rates on the adhesion of solid polymeric surfaces of poly(butylmethacrylate). They used the equilibrium JKR theory of adhesion or contact mechanics as a framework for analyzing the adhesion dynamics of two surfaces during nonequilibrium (viscoelastic, plastic) adhesion and separation. PBMA films of thickness {approximately}2 {micro}m were prepared on curved mica surfaces by casting from a solution of methyl ethyl ketone. Pull-off forces from adhesive contact were measured at different temperatures around the glass-rubber transition temperature (T{sub g} {approx} 25 C) at different loads andmore »« less

Use of capacitance to measure surface forces. 1. Measuring distance of separation with enhanced spatial and time resolution

Journal Article Frantz, P ; Agrait, N ; Salmeron, M ; ... - Langmuir

We describe a simple method to measure the separation and forces between two macroscopic surfaces mounted in a crossed cylinder arrangement. It is shown that by measuring the capacitance between silver layers deposited on the backside of thin mica substrates, it is possible to achieve spatial resolution of less than 0.1 nm and time resolution of 1 ms. The growth of capacitance with decreasing distance of separation follows the predicted dependence for an ideal sphere and plate capacitor. To demonstrate the capability of obtaining force-distance profiles with this technique, octamethylcyclotetrasiloxane (OMCTS) has been confined between the mica sheets. We findmore »« less

A molecular theory for surface forces adhesion measurements

Journal Article Frink, L J ; van Swol, F - Journal of Chemical Physics

Surface forces have been measured by others in undersaturated vapors to determine the adhesive energy of the solid (mica) as well as to probe the limits of the Laplace-Kelvin equation in micropores. The measured pull-off forces are complex requiring an intimate understanding of the underlying oscillatory solvation forces, adsorption, and surface deformation. While the elastic energy of the solid has been taken into account in previous theoretical studies of adhesion, the Laplace-Kelvin assumption of a uniform bulk-like fluid has always been applied. In this paper we present the first application of a modern molecular theory{emdash}a nonlocal density functional theory{emdash}to themore »« less

Surface force measurements and simulations of mussel-derived peptide adhesives on wet organic surfaces

Journal Article Levine, Zachary A. ; Rapp, Michael V. ; Wei, Wei ; ... - Proceedings of the National Academy of Sciences of the United States of America

Translating sticky biological molecules—such as mussel foot proteins (MFPs)—into synthetic, cost-effective underwater adhesives with adjustable nano- and macroscale characteristics requires an intimate understanding of the glue’s molecular interactions. In this paper, to help facilitate the next generation of aqueous adhesives, we performed a combination of surface forces apparatus (SFA) measurements and replica-exchange molecular dynamics (REMD) simulations on a synthetic, easy to prepare, Dopa-containing peptide (MFP-3s peptide), which adheres to organic surfaces just as effectively as its wild-type protein analog. Experiments and simulations both show significant differences in peptide adsorption on CH ₃-terminated (hydrophobic) and OH-terminated (hydrophilic) self-assembled monolayers (SAMs), wheremore »« less
