Chemical and Materials Engineering Faculty Patents
Devices and methods for cutaneous delivery of a composition are provided, wherein the composition is passed through an ordered nanoporous membrane in fluid communication with a reservoir. The nanoporous membrane includes a plurality of aligned hollow nanotubules coated with a continuous polymer matrix, and etched to open the plurality of hollow nanotubules and form pores. In one embodiment, the etching step oxidizes an end of the nanotubules to form carboxylate groups. The ordered nanoporous membrane further includes at least one additional functional unit bound to the carboxylate groups. The at least one additional functional unit selectively exposes or at least …

Functionalized Polymeric Membranes For Bioseparation And Biocatalysis, Saurav Datta
Theses and Dissertations--Chemical and Materials Engineering
Functionalized polymeric membrane based techniques are becoming increasingly popular in biotechnology, food and pharmaceutical industries due to their versatility and hydrodynamic benefits over traditional materials and methods. This research work has been directed towards the development of functionalized polymeric membranes, extensive experimental and theoretical analyses of some of the fundamental aspects of accessibility, membrane fouling and enzyme catalysis, and applications in affinity based bioseparation and biocatalysis. In this research work, the impact of different types of functionalization techniques, such as functionalization of different membrane materials, covalent and electrostatic immobilization, on interaction of various biomolecules and active sites in membrane has …
