Plasma Surface Engineering to Biofunctionalise Polymers for ?-Cell Adhesion

Cell Adhesion to Plasma-Coated PVC

To produce environments suitable for cell culture, thin polymer films were deposited onto commercial PVC plates from radiofrequency acetylene-argon plasmas. The proportion of argon in the plasmas, P(Ar), was varied from 5.3 to 65.8%. The adhesion and growth of Vero cells on the coated surfaces were examined for different incubation times. Cytotoxicity tests were performed using spectroscopic me...

Engineering Cell Adhesion for Applications in Biotechnology

The ability to control the placement of mammalian cells is important for many commercial and research applications. Any attempt to constrain normal mammalian cells will have functional consequences and will require an understanding of the basic mechanisms underlying adhesion between cells and their underlying substratum. We describe the current model of cell adhesion and the use of micropattern...

Plasma-surface Interactions of Model Polymers for Advanced Photoresist Systems

Title of Document: PLASMA-SURFACE INTERACTIONS OF MODEL POLYMERS FOR ADVANCED PHOTORESIST SYSTEMS Sebastian Ulrich Engelmann, Doctor of Philosophy, 2008 Directed By: Professor Gottlieb S. Oehrlein, Department of Material Science and Engineering Plasma processing of advanced photoresist (PR) materials is a critical step in nano-manufacturing. We have studied the interactions of PRs and polymers ...

Engineering Micro - tools in Polymers to Study Cell Biology

Recent advances in surface engineering and soft lithography provide tools to fabricate patterned surfaces and microfluidic devices with dimensions comparable to the sizes of single mammalian cells. These technologies enable the studies of individual cells on spatially well-defined, patterned surfaces, and in contact with patterned liquid media. They provide information about cells impossible to...
