The first synthetic polymer was Bakelite, phenol-formaldehyde resin, developed from 1905-1909 by chemist Leo Baekeland. Since then, polymer chemistry and technology has enhanced our way of life from transportation to food storage to communication and electronics. These advances have breached the barrier of pure polymer science and transcended into the fields of material science, physics, and biology. Currently, innovative research in polymers is enabling the nanotechnology revolution with a focus on the design and production of polymer thin films that have tunable properties. One such thin film is polymer brushes, and it is the focus of this dissertation. Polymer brushes, broadly defined, are an assembly of polymer chains anchored to a surface from some point in the chain, typically the end. They have desirable characteristics such as the ability to tether molecules to a substrate, or change the properties of a surface. Over the years, polymer brushes have found use in a number of applications such as in the development of new adhesive materials, biosurfaces and nonfouling biosurfaces. This work will illustrate several types of biosensors that have been enhanced through the incorporation of polymer brushes as well as investigate brushes as detached membranes. The first biosensor is an electrochemical detector is based on the intrinsic catalytic activity of antibodies. As a means of amplifying the signal, polymer brushes have been integrated to bind the antibodies to the surface as well as to prevent non-specific adsorption of other antibodies or contaminants that may be present in the test fluid. A second device includes a PEDOT:PSS based microelectrode which measures neuronal activities in vivo. This requires the tethering of glucose oxidase by brushes for specific charge exchange reactions to occur between the biological media and the conducting polymer. The third sensor uses functionalized polymer brushes to act as a scaffold for monitoring cellular motility. Lastly, we have developed a method of detaching polymer brushes for further exploration. This method provides the opportunity to test initiator quality, immobilization conditions, optimization parameters, and has provided insight to the nature of polymer brushes in a stretched state.

The present ebook covers the mathematical modeling and numerical simulations of polyelectrolyte brush bilayers under shear motion. The similar conditions could be found in mammalian knee joints. The new findings which is described in the last chapter shows that polymer brush bilayers are useful in lubrication exclusively in the presence of hydrodynamic interactions between monomers. This reveals the significance of interstitial water in knee joint.

This is the third edition of the book which contains ten chapters and it covers my research about polymer brush bilayers under shear. The chapter ten is devoted to polymer brush bilayers under non-equilibrium shear inversion which is very important in studying mammalian synovial joint behavior. In this chapter, it is revealed that the hydrodynamic interactions produce mechanical instabilities in the system while adding electrostatic interactions removes those mechanical instabilities.

Patterned polymer brushes are used in biological applications to enhance cell function and to achieve selective cell growth. These patterned surfaces have a variety of applications, including cell sheet harvesting and tissue engineering. This work describes creation of chemical, topological, and responsive patterns on glass by sequential surface-initiated polymerization of poly(N-isopropylacrylamide)-co-(2-hydroxyethyl methacrylate) (pNIPAM-co-HEMA) and subsequent use of UV lithography to pattern the surface with pNIPAM. The cell adhesion peptide, RGD, is then immobilized on the surface of the copolymer pHEMA via DSC-coupling to spatially enhance cell adhesion properties. By culturing cells at 37 degrees celsius, cells selectively grow on DSC-activated pNIPAM-co-HEMA and not on the block copolymer pNIPAM due to its non-fouling properties at thicknesses greater than 20nm. Selective cell growth of NIH3T3, a mouse embryonic fibroblast cell line, is demonstrated on pNIPAM-co-HEMA/pNIPAM patterns of different dimensions. By lowering cell culture temperatures below the lower critical solution temperature (LCST) we can take advantage of the functionality of pHEMA's hydroxyl group and the thermoresponsive property of pNIPAM in order to detach patterned cell sheets detach from pNIPAM-co-HEMA surface. Thus, we have created a single polymer brush platform that provides both positive and negative tone patterns for cell growth, as well as incorporating thermoresponsive polymers to fine tune surface properties and enable selective detachment of cell sheets, as well as facile modification of non-fouling regions via common and robust DSC-coupling for use in cell sheet engineering applications.
