Chair: Charles R. Martin.

Thesis (Ph.D.)--University of Florida, 2005.

Finally, a new family of protein biosensors based on a single conical nanotube membrane is described. Three different protein systems were investigated: (i) biotin/streptavidin, (ii) protein-G/immunoglobulins, and (iii) anti-ricin/ricin.

520 $a Finally, a new family of protein biosensors based on a single conical nanotube membrane is described. Three different protein systems were investigated: (i) biotin/streptavidin, (ii) protein-G/immunoglobulins, and (iii) anti-ricin/ricin.
520 $a The discovery of novel materials, processes, and phenomena at the nanoscale, as well as the development of new experimental and theoretical techniques for research, provide fresh opportunities for the development of innovative nanodevices and nanostructured materials. Nanostructured materials can be made with unique nanostructures and properties, and finding various and unique applications of these is a continuous challenge for researchers in this field. As part of this emerging research, the work presented here is focused on development of new nanostructures based on nanoporous membranes, and investigation of their applications as sensors and separation devices. A template synthesis method is used to produce nanotubes inside the pores of both aluminum oxide and polymeric membranes. After an introduction in the template synthesis method and the processes of fabrication of the porous membranes, the dissertation is centered on investigating new applications of these nanotube membranes. There are three applications of the nanotube alumina membranes, and one application of the single nanotube polymeric membranes that are explored.
520 $a Porous alumina is used to mimic the function of the ligand-gated ion channel by applying a porous battery cathode film to one face of the hydrophobic membrane and a porous battery anode film to the other face. Hence, in analogy to the naturally occurring channel case, we have a membrane with a built in electrochemical potential difference across the membrane.
520 $a The application of silica nanotube membranes in selective separation of proteins is presented. The membranes were modified with antibodies that selectively bind one analyte. These nanotube systems lead to the transport at much higher rates of the analyte which binds to the membrane.
520 $a Another application studied is the fabrication of the protein microarrays which features a three dimensional substrate based on porous aluminum oxide membranes. These membranes represent distinct microfeatures on a robust platform, and they have cylindrical pores with monodisperse nanoscopic diameters. The advantages of using this substrate and its application in antibody specificity screening are presented.
