cell-mineral interface research programme Cell-Mineral Interface Programme Seminar Series 2006 Zhenyu Zhang, Department of Physics & Astronomy: Interaction Between Poly(N,N-dimethyl acrylamide) (PDMA) and different surfaces In recent years, atomic force microscopy (AFM) has provided a range of new opportunities for viewing and manipulating microbial surfaces in their native environments. A molecular force probe (MFP) is being used in this project to investigate the interaction force between cell and surfaces by stretching the cell from surface. Poly(N,N-dimethyl acrylamide) (PDMA) is a good synthetic polymer to start as model polymer. The statistic analysis of adsorption force between different molecular weight PDMA and silicon oxide surface provides essential information of the polymer-surface interaction. During the adhesion of cells to the surface, a quartz crystal microbalance with dissipation (QCM-D) makes it possible to detect very small mass changes as well as viscoelastic properties at the interface.
