Nanofiber Structures as Mimics for Cellular Membranes

Doktycz M.J., Zhang L., Melechko A.V, Klein K., McKnight T.E., Britt P.F., Guillorn M.A., Merkulov V.I., Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

We are investigating the use of vertically aligned carbon nanofibers (VACNFs) as a material for controlling molecular transport in a manner analogous to natural cell membranes. VACNFs can be synthesized with nanometer scale dimensions, can [...]

Fabrication of Nanopipes using Vertically Aligned Carbon Nanofiber Templates and their Properties

Melechko A.V, McKnight T.E., Guillorn M.A., Ilic B., Merkulov V.I., Doktycz M.J., Warmac B., McCorkle D., Lowndes D.H., Simpson M.L., University of Tennessee, Knoxville, US

Fluidic structures with submicron dimensions have potential applications for sorting DNA molecules, electroanalytical sensing, and detecting and characterizing single molecule events. The fabrication of devices that function on the nanometer scale requires new approaches when [...]

Biomimetic Surface Composite Effects Achieved by Interfering Laser Beams

Liu K.W., Liu Z.F., Daniel C., Liu K.W., Liu Z.F., Mücklich F., Saarland University, DE

It is observed from nature that certain insects possess the optimised surface fixing configurations against sliding and the tree body consists of different kinds of micro/nano-tissues with optimised properties to prevent breaking by wind. The [...]

Structure-Function Relations in Self-Assembled Sphingolipids at Gas-Water Interfaces

Vaknin D., Ames Lab, and Iowa State University, US

The development in understanding cell membrane structure and function has been historically intertwined with that of the monomolecular Langmuir layer of amphiphiles at air-aqueous interfaces. Here, we present synchrotron structural studies of a variety of [...]

A Glucose Biosensor using Au Nanoparticle Modified Glucose Oxidase

Meng X., Ren X., Tang F., Chinese Academy of Sciences, CN

Biosensors have a wide field of potential applications in biotechnology, process control and medicine, mainly for accurate measurement of the analyte concentration of physiological fluid to diagnose some diseases. The development of enzyme-based biosensor technology [...]

MembraneChipTM : Arrays of Natively Displayed Membrane Targets for Novel Drug Discovery

Yamazaki V., Nguyen L.T., Schafer R.J., Ulman N., Groves J.T., Proteomic Systems, Inc., US

For the first time, naturally fluid and functional biological membranes have been integrated into a scaleable system. Previously-inaccessible membrane targets can be presented in their native environment. Domains of membrane targets naturally displayed in cell [...]

Mimicking Immune Processes by Positioning Antibodies on Surfaces — A Nanoengineering Approach

Liu G-y., Liu M., Amro N., Komanicky V., Liu G-y., Liu M., University of California Davis, US

Antibody-antigen interaction is one of the most fundamental biospecific interactions. While the antibody-antigen monovalent and divalent bindings are relatively well-known in solution phase, controlling the valency on surfaces has not been attempted. Using scanning probe [...]
