Cross-Linked Single-Walled Carbon Nanotube Buckypapers and their Composites

Guan J., Jakubinek M.B., Ashrafi B., Johnson M., White M.A., Simard B., National Research Council Canada, CA

Single-walled carbon nanotubes (SWCNT) covalently modified with OH functional groups were assembled into buckypapers through solvent dispersion and vacuum filtration. These SWCNT-OH buckypapers were subsequently crosslinked by wetting with bifunctional linkers followed by hot compression, [...]

Optimization of Phage-Based Magnetoelastic Biosensor Performance

Huang S., Yang H., Johnson M., Wan J., Chen I., Petrenko V.A., Chin B.A., Auburn University, US

A magnetoelastic (ME) platform coated with a bio-molecular recognition element (bacteriophage) for selective and specific recognition of Bacillus anthracis spores is described. ME materials have a mass-sensitive, characteristic, resonant frequency. In response to the binding [...]

Simultaneous Detection of Salmonella typhimurium and Bacillus anthracis Spores Using Phage-Based Magnetoelastic Biosensors

Huang S., Yang H., Johnson M., Chen I., Petrenko V.A., Chin B.A., Auburn University, US

Deliberate contamination of the food supply has become a concern, Salmonella typhimurium and Bacillus anthracis spores being primary pathogens of interest. The objective of this research was to investigate simultaneous detection of these two biological [...]

Wafer Scale Aligned Sub-25nm Metal Nanowires on Silicon (110) using PEDAL Lift-off Process

Sonkusale S.R., Amsinck C.J., Nackashi D.P., Di Spigna N.H., Barlage D., Johnson M., Franzon P.D., North Carolina State University, US

We have demonstrated a new PEDAL process to make sub-25 nm nanowires across the whole wafer. The PEDAL process is useful in the fabrication of metal nanowires directly onto the wafer by doing shadow metalization [...]
