Preparation of some smart PAm-ZTS pH-responsive membranes, via reactions between ZTS and PAm under different conditions, was conducted for testing pressure-driven reverse osmosis membranes (PDROMs) in active rejection of Ce4+, Pr3+, Sm3+, Gd3+, Dy3+, and Ho3+ ionic lanthanide species in their 3+ and 4+ states. Recent theoretical models to designate the membrane operations were mathematically itemized, after selective characterization of the PDROMs. The pH scale response of the membrane was confirmed using static adsorption and hydraulic pervasion result estimations. The flux across the PAm-ZTS membrane decreased with the lowering pH value, with drastic decreases between pH 4 and 7, and was both reversible and durable with pH shifts between ~3 and ~8. At lower pH 3, the individual pores were in a closed-state due to the prolonged structure of the amide chains on the porous surfaces. In contrast, at pH 8, the higher pH value, the membrane pores were in an open-state format, because of the collapsed structures of the amide chains. This grants a clear possible approach for manufacturing some pH-responsive composite membranes and inspires further design for their stimuli-responsive actions by incorporating molecularly designed macromolecules, synthesized by controlled polymerization.

We report the fabrication of microporous thin film membranes with two-dimensionally arranged submicron pores whose size can be varied by changing pH of aqueous medium. A solution containing poly(2-vinylpyridine) partially quaternized with 1,4-dilodobutane (qP2VP) and unreacted 1,4-diodobutane (DIB) was used for the formation and deposition of the membranes on solid substrates. The membranes were spin-coated on to solid substrates in a controlled humid environment. The presence of water vapor in air was found to be a necessary condition for the pore formation. We studied the influence of relative humidity on the membrane morphology and proposed a mechanism of pore formation. Cross-linking the qP2VP membranes with DIB made them insoluble (stable) in organic solvents and acidic water. The cross-linked membranes demonstrated pH-dependent swelling, which had a strong influence on the pore size.

The efficient and safe delivery of complex biological agents offers great potential for the challenges of our time. Polymers offer considerable advantages in this regard, not only because of their low risk for immunogenic reactions, their comparatively inexpensive large-scale production and their long shelf life. The biological properties of organisms, organs, tissues and cells determine the design of safe and efficient delivery systems and should be considered as inspiration for new attempts to create effective materials. In addition to the balance between hydrophobicity and hydrophilicity, the degree of charge of a nanocarrier is also critical for efficient delivery and overcoming the endosome. Cationic charges do not only enhance cellular uptake but can also mediate a crossing of the endosomal barrier due to membrane interactions. The introduction of hydrophobic or even lipophilic components can further significantly increase membrane interactions. Besides the interaction with the cell membrane, it is important to consider that both the degree of charge and the hydrophobic-hydrophilic balance also affect the packaging and protection of sensitive biological cargo such as genetic material. However, cationic charges and hydrophobic components introduce some disadvantages, as electrostatic and hydrophobic interactions may disrupt the integrity of other cellular membranes, triggering toxic effects. Fine adjustment of the degree of charge and the hydrophobic-hydrophilic balance offer the possibility of balancing the requirements for a safe, yet efficient delivery process. In the present dissertation, various polymer systems with adjustable charge density and hydrophobic-hydrophilic balance were investigated with respect to their delivery efficiencies. A particular focus was set on the key step in delivery, the endosomal release.

Biological membranes are extremely complex, highly organized, responsive thin films composed of a myriad of lipids and proteins. Due to their complexity, supported lipid bilayers have been used as alternates to living cell membranes for study of membrane dynamics, membrane structure, and lipid-protein interactions, among other topics. The tools of modern genetic engineering and bioorganic chemistry allow us to couple many types of biomolecule to supported membranes. This results in wide variety of interfaces that can be used to control, organize and study the properties and function of membranes and membrane-associated proteins. The overarching goal has been to develop robust and easily fabricated biomimetic membrane platforms to facilitate the study of transmembrane proteins for sensing applications.Despite the large volume of research, development of solid supported membrane bilayers that recreate the proper environment has proven to be difficult. Some fundamental drawbacks have been protein substrate interactions leading to premature denaturing of the protein and minimal-to-no mobility within the membrane. To ameliorate these issues, polymer supported lipid bilayers are widely used. One of the main attractions for using polymeric cushions is to mimic thermodynamic and structural properties of free bilayer more specifically the cytoskeleton and extra cellular matrix, which is an important feature of the native cellular environment.Chapter 1 describes the fabrication and characterization of polymer supported bilayers and reviews the lateral mobility of the lipids and proteins on various types of polymer supports. Also presented are potential practical applications including biosensors and future directions of development of polymer supported lipid bilayers. Chapter 2 provides the mobility of a polymer supported lipid bilayer with a polymer cushion that is pH responsive and structurally tunable in order to provide an environmentally sensitive interface. In details, the simple preparation of poly(acrylic acid) (PAA) cushioned membranes is described. The PAA cushion provides a tunable, water rich environment for supported lipid membrane applications. Conveniently the thickness of the PAA cushion can be controlled by manipulating the pH of the surrounding aqueous solution and the concentration of the spin-coating solution. As demonstrated in this work, the structure and continuity of cushioned membranes remains intact and this approach offers a robust and facile means to fabricate biological membranes for biophysical studies and sensing applications.
