Atomic 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, ...
متن کاملپراکندگی ژن CtpA در لیستریا مونوسیتوژنزDistribution of ctpA Gene in Listeriamonocytogenes
Background & Aim: Listeria monocytogenes has potentiality to cause serious invasive disease in humans and in more than 40 animal species. L. monocytogenes is transmitted from soft cheese, milk, raw meat and sausages to human. The present study was undertaken to find the frequency of L. monocytogenes in poultry, domestic animals, sausage, cheese, milk, and also to determine ctpA(copper t...
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 کاملExploring mechanism of xanthate adsorption on chalcopyrite surface: An atomic force microscopy study
In this work, adsorption of the potassium amyl xanthate collector on the pure chalcopyrite surface was studied by applying atomic force microscopy (AFM). The adsorption experiments were carried out at different concentrations of the collector and at diverse pH values in the presence or absence of exterior ions. The changes occurring in the surface morphology of chalcopyrite due to the collector...
متن کاملAtomic force microscopy in biomaterials surface science.
Recent progress in surface science, nanotechnology and biophysics has cast new light on the correlation between the physicochemical properties of biomaterials and the resulting biological response. One experimental tool that promises to generate an increasingly more sophisticated knowledge of how proteins, cells and bacteria interact with nanostructured surfaces is the atomic force microscope (...
