Velocity-Dependent Forces in Atomic Force Microscopy Imaging of Lipid Films
We have imaged adsorbed fluid lipid bilayers by atomic force microscopy. The patches were formed by rupture of phospholipid vesicles onto magnesium fluoride. We show that the membrane patches are fluid but can be stably imaged at scan rates higher than 6 p d s . At lower scan rates the tip penetrates through the layer. The penetrating tip does not destroy the fluid patches, and the previous ima...
متن کاملVelocity dependent friction laws in contact mode atomic force microscopy.
Friction forces in the tip-sample contact govern the dynamics of contact mode atomic force microscopy. In ambient conditions typical contact radii between tip and sample are in the order of a few nanometers. In order to account for the large interaction area the dynamics of contact mode atomic force microscope (AFM) is investigated under the assumption of a multi-asperity contact interface betw...
متن کاملSurface Evaluation of Resin Zein Films Containing Sugar Plasticizers by Permeability and Atomic Force Microscopy Analysis
Zein is one of the best biopolymer for edible film making and sugars are natural plasticizers for biopolymers. In this research, sugars (fructose, galactose and glucose) at three levels (0.5, 0.7, 1 g/g of zein) were used as plasticizers for zein protein films and their water vapor permeability (WVP), oxygen permeability (OP) and atomic force microscopy (AFM) topography were studied. The p...
متن کاملEquilibrium capillary forces with atomic force microscopy.
We present measurements of equilibrium forces resulting from capillary condensation. The results give access to the ultralow interfacial tensions between the capillary bridge and the coexisting bulk phase. We demonstrate this with solutions of associative polymers and an aqueous mixture of gelatin and dextran, with interfacial tensions around 10 microN/m. The equilibrium nature of the capillary...
متن کاملAtomic Force Microscopy Application in Biological Research: A Review Study
Atomic force microscopy (AFM) is a three-dimensional topographic technique with a high atomic resolution to measure surface roughness. AFM is a kind of scanning probe microscope, and its near-field technique is based on the interaction between a sharp tip and the atoms of the sample surface. There are several methods and many ways to modify the tip of the AFM to investigate surface properties, ...
