Kinetics study of carbon nanotube alignment under shear force via real-time polarized Raman spectroscopy

He Y., Taub A.I., University of Michigan-Ann Arbor, US

Carbon nanotubes (CNTs) have been studied extensively since their discovery by Iijima in 1991. They have a unique quasi one-dimensional nanoscale structure with remarkable mechanical, electrical and thermal properties. Numerous investigations have been done on [...]

Real-Time Electronic Detection of Water/Food Borne Pathogens

Potter M., BiSen Tech LLC, US

Current methods for detecting water-borne pathogens require a laboratory setting, analyte preparation and typically a day or more. The author, a solid state device physicist, has invented a methodology capable of the real-time (1 - [...]

Label-free direct detection of analytes from optically inaccessible samples

Brousseau L.C., Quantum Logic Devices, US

Fluorescent optical methods for biomolecular detection are widely used for research and diagnostic applications. However, these techniques are useful only in sample matrices that are optically transparent non-scattering, which precludes most biologically relevant fluids, such [...]

Real-time single-molecule dynamics observed with a nanoscale transistor

Brousseau L.C., Quantum Logic Devices, US

Direct observation of single molecular reactions and motions are impossible by optical techniques due to diffraction limits. However, ensemble measurements of binding dynamics in biological systems offer limited understanding of individual actors in metabolic and [...]

Real-Time In-Situ Measurement of Nanoparticle Size Distributions Using Electrical Mobility Technique

Kathleen E., Osmondson B., Singh M., TSI Incorporated, US

Electrical Mobility Technique for real-time sizing of aerosolized nanoparticles is described. Case studies of measurement of nanoparticles using electrical mobility and comparison of results with Scanning Electron Microscopy are shown.
